5 types of glass crusher for sale | fote machinery

5 types of glass crusher for sale | fote machinery

Glass is one of the commonly used material in people's production and daily life. It is widely used in construction, chemical, medical, automotive, engineering, instrumentation, and other industries.

Waste glass is on the rise due to the popularization of glass. Meanwhile, the recycling of glass waste reduces the discharge of garbage, achieves the goal of environmental protection, and brings good benefits for investment users.

The glass crusher can process various waste glass such as glass pieces, glass bottles, automobile glass, bulletproof glass, industrial glass tubes, and other glass products into various shapes of granular, fibrous, powdery, etc.

The traditional jaw crusher is a primary crushing equipment, and Fote Heavy Machinery has improved the jaw crusher in its design so that it can be used for fine crushing and suitable for glass recycling.

Since Fote jaw crusher has a deep crushing cavity, glass can be crushed and processed by squeezing, grinding and other methods. At the same time, glass jaw crusher has the characteristics of large crushing ratio and a wide range of application which can crush various glass such as beer bottles and automobile glass with different hardness.

Given that glass is a highly brittle material thatmay cause some splashes during the crushing process, Fote glass jaw crusher has been designed with a semi-closed vertical curtain at the feeding port, which can prevent the splash of materials, and play the role of noise reduction and dust sealing.

Theglass jaw crusher is the highly productive equipment with the capacity of1 to 500 tons per hour. And the glass crushing machine has a complete model series to meet the different needs of customers.

The glass can be easily crushed by the impact force produced by the high-speed hammerhead of the glass hammer crusher. Simultaneously, this work requires the hammerhead to have strong wear resistance.

The gap of the grate at the discharge port can be adjusted to control the product size. The glass crusher has a wide range of adaptation, advanced structural design, good sealing of frame, and produces low noise and little pollution.

Glass roll crusher has a simple design, a small footprint, and is easy to install and replace its components. It is equipped with a dustproof board, improving the sealing performance and avoiding the splash of glass dust.

The glass impact crusher can handle glass waste with large water content, if the glass material contains too much water, it could be reduced by the heating device installed on the feeding port and impact plate.

Glass impact crusher can effectively control the discharge particle size and has a wide adjusting range of discharging port. It can control the output size by adjusting the rotor speed, the impact type and the gap of the grinding chamber.

The glass crushing process has very little wear on the impact crusher. When the glass material is broken by the impact crusher, it will hit the front of the hammer plate without any touch with the back and sides of the machine.

Due to the large hammerhead of the impact crusher, its balance needs to be calibrated during installation, otherwise, the vibration force of the machine will be relatively large during operation, which may be dangerous.

The working performance of the glass compound crusher is less affected by the moisture of the material. The finished product is cubic and has large bulk density and small iron pollution, which will improve the recycling value of glass wastes.

The glass composite crusher is designed with a vertical structure, so the material may not be repeatedly crushed at a fast-passing speed, and a good crushing effect cannot be guaranteed for glass pieces.

The working mode of the crusher and the daily maintenance can respectively control and influence the crushing performance. Each type of crusher has different parameters such as crushing principle, feeding and output size.

jaw crusher liner plate design & profile shapes

jaw crusher liner plate design & profile shapes

Straight Jaw Plates:Ashows a diagram of a standard type of Blake crusher with regular or straight jaw plates. This type of plate has been the standard from the time of its inception, emulating, in this respect, the straight concaves in the gyratory machine. And it will be noted that the theoretical action in this straight-plate jaw chamber follows quite closely the pattern of the action in the straight-concave gyratory chamber.

Calculations for the jaw crusher chamber are somewhat simpler than in the case of the gyratory because the volumes included between the successive pairs of horizontal lines are rectangular in plan, whereas, in the gyratory we have to deal with annular volumes (actually, a descending spiral, rather than flat rings). But, when the line-of-mean-diameters in the gyratory chamber parallels to a close approximation, at least the centerline of the crusher, the general characteristics of the two crushing chambers, with respect to ratio-of-volume reduction and concomitant reduction in percentage of voids are similar. Crushing angles and throws would of course have to be the same for the comparison to be exact.

There is one readily discernible difference between the two diagrams we are comparing; the drop per stroke in the jaw crusher diagram is noticeably smaller. This difference is most pronounced in the upper part of the chamber. The reason for the difference is two-fold. In the particular machines selected for these diagrams, there is a difference of several degrees of crushing angle in favor of thegyratory; this accounts for the average difference over the full depth of the chambers. Secondly, the motion of the swing jaw, at the top of the crushing chamber is, proportionately, smaller than the movement at the top of the gyratory chamber. The reason for this is that the distance from the top of the crushing chamber to the fulcrum-pointas compared to the total length from discharge-point to fulcrum-point is smaller in the case of the jaw crusher. This is generally true of Blake-type crushers as compared to gyratories except for the vertical swing jaw type, in which the swing jaw is carried up some distance above the top of the stationary jaw.

The close proximity of the fulcrum-point to the receiving opening gives the type of crusher we are considering enormous leverage on large blocks of stone, and the small motion tends to decrease the shocks incidental to gripping and shattering such blocks. From the capacity standpoint, the smaller drop per stroke is compensated for by the fact that the jaw crusher speed, for comparable sizes, is higher than the eccentric-speed of the gyratory.

Non-choking Jaw Plates:When the non-choking concave demonstrated its capabilities in the gyratory crusher, it was only natural that the principle should be applied to the jaw crusher. But, inasmuch as the Blake-type jaw is used very largely for primary breaking, where maximum receiving opening is, more often than not, a controlling factor, the application of non-choking plates to standard machines of this type has one unfavorable aspect, as will be evident from an examination of BStandard Blake jaw crusher non-choking swing jaw plate. This diagram shows the same machine asthe last one considered, except that the swing jaw is fitted with a curved jaw plate.

These non-choking jaw plates have been developed in two styles, reversible and non-reversible. The advantage of the reversible design has been outlined in connection with its application to the gyratory reduction crusher. For both types of jaw plate, the effective receiving opening is reduced, as compared to the standard, straight-plate setup. For the non-reversible plate, this reduction is determined by the actual increase in depth of the plate, resulting from the introduction of the curve. For the reversible plate, it is established by the point where the tangent to the curved surface coincides with the maximum angle of nip for the material being crushed. Similar restrictions were outlined in our discussion of non-choking concaves in gyratory crushers.

Regarding the reversible plate, it should be noted that, while that portion of the chamber above the point of nip does no crushing, it does constitute an active receiving hopper and, as such, is of definite value in minimizing bridging across the receiving opening. For applications which do not require the full rated receiving opening of the crusher, non-choking jaw plates offer a substantial improvement in performance, an improvement comparable to that resulting from the substitution of non-choking concaves in the gyratory crusher. While this is readily apparent from a comparison of the two diagrams we have presented, more concrete evidence is contained in the table of capacity ratings, which gives ratings for both types of jaw plates, for sizes up to, and including, the 6048 machine.

jaw crushers for sale

jaw crushers for sale

The jaw crushers we offer for sale include Superior, Type B Blake, Fine-Reduction, and Dodge sizes, 4 by 6 to 84 by 66 inches. A reciprocating machine, the crushes material in a straight line between jaws without grinding or rubbing surfaces.

As you compare this jaw crusher feature for feature with other makes youll see how this modern crusher lowers principal costspower consumption; lubrication; jaw plate, toggle plate, and bearing wear youll understand why we say the crusher promises you a new low cost per ton of material crushed!

Firstthose who have rock or ore tougher and more abrasive than most material. Secondthe operators whove had difficulty with other designs of crushers. And finallythe operators who naturally buy the bestexpecting their added investment to be written off in comparatively short time through lower operating and maintenance costs!

Compare the dimensions with those of conventional jaw crushers. It measures up to 20% longer; has up to 35% deeper crushing chamber! And while you naturally expect to pay more for this bigger,deluxe crusher, it follows that you get more too! For example:

You get a crushing chamber with a full-width receiving opening increased capacity! You get an acute crushing chamber that minimizes slippage very important with hard, tough materials. You cut down crushing power required through longer pitman and front toggle. You reduce packing, get closer setting through the longer jaw, non-choking plates. You lower maintenance cost, get longer jaw plate, toggle, and bearing life through lower structural stresses, simplified design.

Frames of these crushers are built for maximum rigidity designed to prevent distortion during operation. Side members are heavy steel plate, reinforced by steel ribbing. End members are cast steel, of box section design, to provide maximum strength.

The side frames are deep-welded and then stress-relieved in thehuge annealing furnaces to eliminate possible failure adjacent to welds. The result is a uniformly strong frame that will remain true during the long service life of the crusher.

A jaw crusher frames are of sectionalized construction to facilitate handling. This design minimizes heavy lifts makes the crusher suitable for installations where parts must be passed down a shaft or through a tunnel. End members are attached between side members with vertical tongue and groove joints and held together with fitted bolts. Long-bearing surfaces prevent angular distortion.

Important differences in design show up visually when a cross-section of the crushing chamber of a conventional crusher is superimposed over that of the crusher. Now you can see the advantages of the 1 /3 deeper chamber using non-choking jaw plates. Its more acute crushing angle is carried to the very top of the chamberpermits nipping the largest material that can enter the receiving opening!

Lower plates on the swing and stationary jaws are suspended from projections on jaws. These plates also support the upper plates. This exclusive feature permits the free expansion of manganese steel jaw plates greatly minimizes the possibility of buckling or warping prevents costly shutdowns!

SWING AND STATIONARY JAWS on the jaw crusher are annealed cast steel box section construction designed for maximum rigidity. The jaw swings on a sturdy shaft that is clamped to the crusher frame. This shaft also serves as a reinforcing tie across the top of the frame. The entire design facilitates lubrication and replacement of shaft bearings.

Jaw plates are constructed of manganese steel and have corrugated crushing surfaces which reduce the power required for fracturing material. The jaw plates are built into two pieces to jaw. Those on the swing jaw are interchangeable. Plates on the stationary jaw are the non-choking type, not interchangeable. Lower plates on both jaws are suspended from jaw projections and support upper plates. The main advantage of this construction (see above) is to permit the free flow of manganese steel. All four plates are held in place by large through-bolts equipped with springs to prevent bolt breakage.

Heres still another feature youll find on the jaw crusher! Renewable wearing plates between the cast manganese steel jaw plates and swing and stationary jaws provide a firm backing for the jaw plates. If, for any reason, looseness develops in the jaw plates, these wearing plates, not the jaws, take the wear! By protecting expensive jaw castings, these wearing plates increase crusher life simplify maintenance minimize causes for shutdowns.

The heavy, two-piece corrugated manganese steel jaw plate is designed to fracture the toughest kinds of rock or ore with a minimum of power. The unobstructed clearances above, between, and below the plate sections permit free flow of manganese steel.

This construction eliminates the need for extra holding pieces, greatly minimizes the shearing of bolts. The amply designed shaft not only supports the swing jaw but reinforces the frame, serving as a tie between sides.

Notice the extra length of this jaw as compared to conventional types. Designed up to one-third longer, it exerts greater pressures in the upper portion of the crushing chamber, distributes crushing action more evenly. The result is a gradual reduction of ore to the choking point, and increased capacity!

Another, southern iron ore mining company, chose this 48 by 42-inch crusher to replace a conventional design that had failed. They explained, In our process, weve got to have a ruggedly designed crusher capable of continuous operation!

CRUSHERSin sizes from 36 by 25 to 60 by 48 inchesare giving these and other operators more for their money more capacity; more crusher life; more satisfaction! It can pay you too, to know more about this great crusher! Why not call in your use today!

All sizes of crushers feature a three-piece toggle plate construction. Worn ends may be replaced no need to discard the entire toggle. Bronze toggle ends fit into replaceable hardened steel toggle seats in swing jaw. Properly lubricated, this assembly materially reduces maintenance.

Toggle plates for these jaw crushers are of three-piece construction, consisting of an iron center section (2) to which are bolted two replaceable bronze ends (1 and 3). Toggle seats are carefully machined and equipped with protecting shields that deflect dust and dirt.

A toggle block, arranged for both vertical and horizontal adjustment, is provided at the rear of the frame. By inserting shims above the toggle block, the crushing stroke can be adjusted. Insertion of shims behind the toggle block adjusts the size of the discharge opening. Parallel alignment is assured and unnecessary strain in the crushing machine is avoided.

The pitman in any jaw crusher is essentially a tension member. However, because it also has a vertical reciprocating movement, it is desirable to keep its weight as low as possible, consistent with maintaining the required strength.

In the crusher this is accomplished by designing the pitman as a skeleton member, first to provide the necessary strength for tension and with stiffness against overturning thrust provided for by deep integral webs.

The pitman is designed with only four large-cap bolts, and the pitman cap is ribbed for proper distribution of the load to these bolts. The pitman is swung on the eccentric shaft which is supported by removable, water-cooled bearings on the frame.

The pitman is a two-piece annealed cast steel construction, with a cap designed for water cooling. Bearing surfaces on both pitman and cap are babbitted and are joined together by four large forged steel bolts. The elimination of excess bolts inherently found in conventional design results in a more uniform distribution of load.

The pitman (eccentric) shaft is heat-treated, forged steel constructionof ample diameter so that stress, even under the shock of suddenly clogged jaws, is low. The shaft is carried in removable, water-cooled, babbitted bearings designed to permit quick removal or replacement without having to strip the crusher.

Heres a typical toggle plate for jaw crushers. It is constructed in three pieceswith the center section of iron, two ends of bronze, designed for quick bolting to the center section. This unique construction materially reduces replacement and maintenance costs makes it unnecessary to discard toggles when ends alone are worn!

A critical point in the operation of large jaw crushers is the arrangement of the swing jaw and its supporting shaft. While in most crushers the jaw is pressed on the shaft and the latter swings in frame, in the jaw crusher the opposite principle is usedshaft is clamped in frame and jaw swings on the shaft!

Another point has been lubrication. In operation, the actual movement of the swing jaw is relatively small. The result is difficulty in proper lubrication of bearing surfaces. The crusher uses a special means of lubrication and in addition is designed with the new replaceable, graphite-impregnated Scor-proof bushings which greatly reduce wear on the expensive shaftssince these bushings, and not the shaft, now take the wear!

Very careful attention is required in the lubrication of heavy mechanical units like the jaw crusher. A thorough study made of existing types of lubrication systems resulted in the selection of a pair of systems that assure positive delivery of lubricant to point of maximum pressure.

The 48 by 42-inch jaw crusher and smaller sizes are force-fed by an automatic high-pressure lubricator to the swing jaw, pitman, and main bearings as illustrated in Figure 1. A motor-driven pump forces the lubricant through pressure buildup cylinders and out to distributors which dispense a precise amount to each of the points on the bearings. No oil return is provided.

The 60 by 48-inch jaw crusher and larger sizes are lubricated by a closed circuit oiling system to the pitman and main bearings, as illustrated by the solid lines in Figure 2, and by high-pressure lubrication fittings connected to the swing jaw bearings, as illustrated by the dotted lines in Figure 2. A motor-driven gear pump forces the oil through pressure-type filters and a condenser-type cooler to a distribution manifold mounted on the crusher. The oil flows through the bearings, lubricating and cooling, and back to the reservoir for recirculation. The swing jaw bearings require servicing by portable grease equipment.

The capacity of the jaw crusher is greater than that of conventional jaw crushers. One reason is its uniform-wear crushing chamber with full-width receiving opening. Another reasonits a more acute crushing angle.

Slippage is reduced packing and choking are prevented by a more even distribution of crushing action throughout the entire length of the crushing chamber. The result is a gradual reduction of material to the choking point increased capacity!

Capacities given below are approximate and are based on standard speeds, jaw motions, and jaw plates, with a feed of quarry or mine run material weighing 100 lb per cu ft crushed. Most stone and low-grade ores are considered weighing 100 lb per cu ft crushed.

The table is based on continuous feeding. Reserve for normal interruption of feeding should be provided. A heavy-duty apron feeder is recommended for most installations, particularly where large cars or trucks are used in the quarry or mine.

When feed to crushers is scalped over grizzlies or screens the number of rejections, or material that will have to be crushed should be determined in establishing the tonnage to be handled by the crusher. The number of fines received from mine or quarry will vary widely depending on each application and should be taken into consideration in determining the overall capacity.

Whatever equipment you operate, you can be certain of careful, considerate handling of orders for repair or replacement parts. In most cases parts are shipped directly from stockyoure assured of fast delivery. The view at left shows a small portion of crushing, cement, and mining equipment parts normally carries.

Repair parts temporarily depleted or not carried in stock will be furnished in time to meet requirements whenever possible. Anticipation of future needs, placing orders in advance, will greatly aid in avoiding unforeseen delays. Genuine parts are exact duplicates or improvements of original components of your machinery, not makeshift substitutes.

jaw plate crusher jaw plate price discount - eb castworld % jaw plate

Leading supplier of high alloy castings and forgings. There are 4 companies with sales of more than 100 million yuan, across the 4 major areas of wear resistance, heat resistance, corrosion resistance, and machinery

The jaw plate of the jaw plate crusher is referred to as the jaw plate. The jaw plate is divided into a fixed jaw plate and a movable jaw plate. It is a wear-resistant part of the jaw crusher. In the operating state of the jaw crusher, the movable jaw is attached to the movable jaw to make a compound pendulum movement, forming an angle with the fixed jaw to squeeze the stone. Therefore, the jaw plate is a more easily damaged accessory (abbreviated as: vulnerable part) in the jaw crusher.

Classification: Fixed jaw and movable jaw Composition: The composition of the working cavity composed of moving and fixed jaws Jaw plate is the main wear-resistant part of the jaw crusher: the movable jaw plate and the static jaw plate.

In the design, the crushing plate of the movable and fixed jaws should be tooth peak to tooth valley. Addition to the squeezing effect, the material has a bending effect when crushing the material, and the material is relatively easy to be broken.

In order to strengthen the service life of the crushing plate, the crushing plate of the small and medium-sized crusher is designed to be symmetrical up and down, and the head can be adjusted when the lower part is worn; the crushing plate of the large jaw crusher is designed to be symmetrical to each other, so that it can be worn after wear. Replace the broken plate The material of the crushing plate can be white cast iron. White cast iron has higher hardness, better wear resistance, easy source, and low price; the disadvantage is that it is brittle, easy to break, and has a short service life. Order to improve the service life of the crushing plate, it is better to use manganese steel with a manganese content of more than 12%, and ZGMn13 is commonly used.

Although the hardness is not high (about 210 HB), but because of the characteristics of cold work hardening, it will continue to be strengthened under pressure, so it will continue to wear and strengthen during work until it is worn out. Use it to be scrapped.

After casting, the manganese steel crushing plate must be treated with water toughening. Operation of the water toughening treatment is basically the same as that of quenching, that is, the cast manganese steel crushing plate is heated to 1 000 to 1 100 and then rapidly cooled in water. After water toughening treatment, a uniform metallographic structure can be obtained, and the metallographic structure can be fixed, avoiding the natural phase change in use and the deterioration of performance. Disadvantage of manganese steel is that it is more expensive, but from the overall consideration of service life and cost, ZGMn13 has a longer service life and lower cost than white cast iron.

Jaw plate is the main wear-resistant part of the jaw crusher: the movable jaw plate and the static jaw plate. According to the different types of the jaw crusher, there are various models and sizes. The jaw plate is made of new high manganese steel, super high manganese steel, Super high manganese steel and other materials are suitable for jaw crushers of various specifications. The jaw crusher is composed of a working cavity composed of movable and fixed jaws. Movable and fixed jaws bear huge crushing force and friction of materials, and are easily worn out. In order to protect the jaw plate, it is generally used in the movable and fixed jaws. A wear-resistant liner is installed on the surface, which is also called a crushing plate.

Surface of the crushing plate is usually made into a tooth shape, and the angle of the tooth peak of the crushing plate is 90120, and its size is determined by the nature and lumpness of the material to be crushed. When crushing large pieces of material, the angle should be larger; Angle can be smaller when it is a piece of material. The size of the tooth pitch depends on the particle size of the product, and is usually approximately equal to the width of the discharge port, the ratio of the tooth height to the tooth pitch can be taken as 1/21/3.

wear speed of the upper and lower parts of the crushing plate is different, the lower part wears faster than the upper part. When the jaw crusher is working, the crushing plate directly contacts the material and bears the huge crushing force and friction of the material, the service life of the crushing plate is directly related to the work efficiency and production cost of the jaw crusher. Therefore, it is particularly important to extend the service life of the crushing plate of the jaw crusher. Strengthening the service life of the jaw crushers crushing plate can be considered from the aspects of design, material selection, assembly and improvement during use.

Biggest consumption in the production of a crusher is the jaw, so the quality must be checked in the selection of talents. It can also be said that the quality of a crusher is actually based on the service life of the jaw. Shell is generally not easily damaged.

jaw crusher | primary crusher in mining & aggregate - jxsc mine

Product Introduction JXSC jaw type rock crusher is usually used as a primary crusher and secondary crusher to reduce the size of medium-hard materials to smaller physical size. Jaw rock crushers are capable of working with the mobile crushing station, underground crushing because of its related small volume. Capacity: 1-1120TPH Max Feeding Size: 120-1200mm Application Mining, metallurgy, building materials, quarrying, gravel & sand making, aggregate processing, recycling, road and railway construction and chemical industry, etc. Suitable Material Granite, marble,basalt, limestone, coal, quartz, pebble, iron ore, copper ore, etc.

40 years of manufacturing and engineering experience keep us innovative and knowledge in the rock break machines and its applications, which thus provide reliable industry rocks crushers and solutions for every customer using jaw crusher manufacturers JXSC machines to meet their production goals. The jaw crusher machine family consists of different sized models that are designed to bring maximum output with minimum cost. Some workplaces have limited conditions and are unable to provide electricity or are underpowered. According to these conditions, JXSC specially designed diesel jaw crusher. The diesel-jaw crusher is actually with electric, but the original jaw crusher was added with a diesel engine equipment that a dual-purpose crusher.

JXSC the crushers machine with a non-welded frame has been proved that it has outstanding solid and durable strength. All the alloy casting frame components turn out that with premium quality, wear-resistant property.

The design of pitman and long stoke improves productivity and reduction. A wider feeding material opening increases the volume of insulating material and makes the ore material entering the crushers crushing chamber smoothly. A sharp angle makes the materials flow down speed faster and reduces the wear cost. Besides, the strike force could be stronger thus increase the production efficiency as well as the reduction ratio.

Types of jaw crushers: on the basis of the stone break equipment size and capacity can divide into a heavy and small(mini) portable jaw rock crushers. According to the working principle can be split into single toggle and double toggle jaw rock crushers machine.

A series of jaw stone crushers use compressive and squeezing force for reducing materials. This physical force is created by the two jaw plates, one of which is a movable plate and another is fixed, both of them are made of manganese. A V-shaped cavity, crushing chamber, is formed and the hydraulic discharge gap width of the crushing chamber, we can determine the suited feeding material size and discharging size, the width of top feeding is larger than that of bottom discharging.

Jaw crusher is a heavy-duty machine that crushes hard materials. So its hence muse be robustly constructed. Crusher frame is made from steel or cast iron. The jaws are made of cast steel. The liners are made fromNi-hard, Ni-Cr alloyed cast iron or manganese steel which can replaceable and use to reduce frame wear. The cheek plates are also made from hard alloy steel and installed to the sides of the crushing chamber to protect the frame from wear.

The jaws can be made in smooth or corrugated, but often corrugated. Because the latter crushing the hard and abrasive ores is better. The angle between the jaws is usually less than 26. This is because a large angle will cause the particle to slip which non-crush.

It uses curved plates to avoid the near the discharge of jaw crusher blocking. The bottom of the swinging jaw is concave, and the relative lower part of the fixed jaw is convex. The materials reduction in size when nears the exit. So the material is distributed over a larger area, and the jaws plates wear less.

The type of crushed materials determines how to design the max amplitude of swing of the jaw and the amplitude adjusted by changing the eccentric. The length from 1 to 7 cm depends on the crusher machine size. Jaw crushers are supplied in sizes up to 1,600 mm (gape)1,900 mm (width). For coarse crushing application (closed set~300 mm), capacities range up to 1200 tph.

Jaw crusher parts must have some wear after a period of use, but the easily damaged parts will wear out more. The price of crushing equipment with the same specifications and handling capacity is different in the material of parts.

Guard Plate The guard plate is made of high-quality high manganese steel, which is located between the fixed plate and the movable plate. The whole body is mainly to protect the jaw crusher frame wall.

Toothed Plate Tooth plate is divided into movable and fixed tooth plate, but both is made from high manganese steel casting. In order to prolong its service life, its shape is designed to be symmetrical. That is when one end of the wear can be used to turn the head. The movable and the fixed teeth plate are the main parts for stone crushing. So the movable teeth plate is installed on the movable jaw to protect the movable jaw.

Toggle Plate The toggle plate is a cast iron piece that has been precisely calculated. It is not only a force transmission component but also the safety parts of the crusher. When the crusher falls into the non-crushing material and makes the machine beyond the normal load, the toggle plate will immediately break. Then the crusher machine stops operation, thus avoiding the damage of the whole machine. The toggle plate and the toggle plate spacer adopt the rolling contact model which less attrition under normal use. It just needs smear a layer of grease on the contact surface is ok.

Triangular Belt When the motor transmits power, the triangle belt is connected with the pulley and the grooved pulley of the motor to drive the eccentric shaft and make the moving jaw move back and forth according to the predetermined track.

The tooth plate of the most jaw crushers are made of manganese steel, bearing linings are made of babbitt alloy, sliding blocks are made of carbon steel, toggle plates are made of cast iron, springs are made of 60SiMn. Regular Inspection and maintenance of the machine can extend its service life. In order to reduce customer costs, we will generally be in the purchase of customers are advised to buy some spare parts. Because once the parts need to be replaced, the temporary purchase will take some time. The wait time may cause the entire breakage line to suspend operations, thereby increasing operating costs.

In short, the jaw stone crushers are mainly used for primary crusher, the crushing stone is relatively large. The types of crusher machine's chamber are deep and no dead zone. It improves that the feeding capacity and output. The crushing ratio is large and the product particle size is even. Shim type outlet adjustment device, reliable and convenient, large hydraulic adjustment range that increased the flexibility of the equipment. Simple structure, reliable work and low operation cost.

Besides, mobile jaw crushers' flexible movement can save lots of manpower and material resources, improving the crushing efficiency. Hongxing mobile jaw crusher has achieved lots of good comments because of its excellent mining properties.

The mobile jaw crusher is also called the portable jaw crusher, tracked mobile jaw crusher. Because of its simple structure, excellent performance, and easy maintenance, as well as less production and construction cost, mobile jaw crusher is still widely used in aggregate quarries, products recycling processing, building materials, electricity, transportation and other industries.

Mobile jaw crusher is developed on the basis of the previous jaw crushers, so there is same function between. This mining and crushing equipment is also applied in breaking thick, medium, and fine ores and rocks with compressive strength in 147-245mpa. In order to meet the needs of high strength and hardness of final products, the mobile jaw crusher equipment has been investing a lot of manpower, and financial resources in the research and development of a new type of mobile jaw crusher with high efficiency and energy saving. More and more new German mobile jaw crusher, CJ European mobile jaw crusher and other series of mining products have been launched.

The crawler mobile jaw crushing equipment runs in the way of curved extrusion. The working principle is that the motor drives the belt and pulley, and moves the mobile jaw up and down through the eccentric shaft. When the mobile jaw rises, the angle between the elbow plate and the mobile jaw becomes larger, so that the mobile jaw plate is close to the fixed jaw plate.

At the same time, the material is crushed or chopped to achieve the purpose of crushing. When the mobile jaw goes down, the angle between the elbow plate and the mobile jaw becomes smaller, and the movable jaw leaves the fixed jaw under the action of the pull rod and the spring, and then the crushed materials come out of the lower opening of the crushing chamber. In general, the output of the mobile jaw crusher is 85-650 tons per hour. And itadopts an integrated group operation mode, which can work separately, eliminating the complex site infrastructure and auxiliary facilities installation work of the split components, and reducing the labor consumption. So, the mobile jaw crusher equipment is suitable for construction waste processing and recycling.

Hongxing mobile jaw crushing and mining equipment is widely used in the crushing of mine rock and ore, stone processing, peeling crushing of cement concrete, crushing of asphalt concrete before regeneration, and crushing of cement concrete construction waste, and so on.

The high-power hydraulic transmission of the mobile jaw crusher fully ensures the accurate control and reverse operation of the crusher to remove blockage when the construction waste and solid waste are broken.

Crawler mobile crushing equipment is composed of receiving system, feeding system, crushing system, power system, transportation system, walking system, hydraulic system and so on. Among them, the power system is the "heart" of crawler mobile stone crusher plant, which mainly has five driving modes: direct drive+ hydraulic drive, direct drive+electric drive, full hydraulic drive, municipal electric drive, diesel electric drive and so on.

The crushing machine has the characteristics of free movement, flexible transition, convenient operation,small covering area and so on with no damage to the road surface and no need of raw materials transportation. Besides, the portable jaw stone crusher plant doesn't slip even in winter, it doesn't have to hit a pile, and it's not demanding in the workplace.

Mobile jaw crusher can use both electricity and oil to drive the equipment, and it can work normally even in bad weather. The mobile jaw crusher is equipped with a market-leading hydraulic jaw crusher, which as the host crusher on the crawler chassis. The unit is integrated and the combination is reasonable and compact.

Diesel electric drive mode is like plug-in hybrid drive of automobile, which is the development direction of crawler mobile crushing plant. This kind of driving crawler mobile crushing plant can be connected to the market in large projects to reduce the cost of use, and diesel engines can be used in small projects, which is flexible and convenient to use.

jaw plate failure and life - crushing, screening & conveying - metallurgist & mineral processing engineer

jaw plate failure and life - crushing, screening & conveying - metallurgist & mineral processing engineer

What is the root cause of jaw plate that has a very short life span, failure rate is bad. I hope we can improve the liners life, I will inform you all if their is a progress on our Jaw liner. thank you so much.

The abrasion index of the material, the feed presentation and size of feed and profile of the jaw all have an impact on wear. If you send me a photo or sketch of the wear pattern I am sure I can offer you some additional advice

We cannot rule out the manganese Jaws themselves as being poorly manufactured i.e. incorrect methods/risers, poor chemistry control and or Heat Treatment issues. We at crushing Equipment would be happy to assist as advisedby Helena.

How have you bench-marked the performance of the liners you are using. Do you have any historic Tonnes per liner data? Has the feed source changed? Have you changed jaw liner suppliers? Has your liner supplier changed the Manganese content of the liners supplied?

There have many causes to make jaw plate short life. It mainly depends on your rock hardness and your crusher working conditions (wet, dry, etc.). You should make sure the jaw plate you bought is good quality. Usually our customer use Mn18% with Cr2%. In order to help customer to improve the jaw plate's lifetime, we have our special material with 20 years experience, such as adding some %Molybdenumwithspecialheat treatment, the jaw plate can increase about20%lifetime. Hope this can help you.

The comments you received so far is spot on. Jaw plate wear is dependent on the type of material you are crushing and other variables like material size. You will want to reduce the amount of fines that enter into the crusher like with the use of a grizzly feeder. Too many fines can accelerate jaw plate wear. What happens is the fines will fill the jaw plate corrugations or valleys. These valleys are necessary for the crusher to crush efficiently. Filling the valleys with fines creates an event called compaction. Normally a jaw crusher will squeeze the material between the stationary and moving jaw plates. The peaks and valleys of the jaw plates are offset from one another and use the mechanical advantage of leverage to break the rock. Without this the crusher has to rely on energy and friction to crush the rock. Compaction will also impose increased loads to the crusher as much as five times the normal crushing force. To the opposite,feed material that is too large also affects wear life. A jaw crusher in most applications is a 6 to 1 ratio of feed reduction. Exceeding the reduction ratio can create crushing forces that can exceed the crushers design limits and will affect your overall production and machine performance. With theover-sizedfeed material you will have a tendency toscrub the material until the jaw plate can get a bite on it. This will also accelerate wear.

If you are using dust suppression it to can also be a factor. Water is actually very abrasive and will accelerate plate wear. If you are using dust suppression you should keep in mind that the dust is better controlled by using a fine spray as appose to using a stream of water. Match the water to the dust and you will control more dust and use less water. Also more dust is present at the discharge than the inlet so water nozzle placement is very crucial to controlling dust without causing accelerated wear.

Like several have mentioned already buying quality is very important. Your supplier should be able to tell you what metal composition your jaw plate is made off. Getting the "right tool for the job" in regards to a good quality jaw plate will give the best performance and longevity.

He is also right about the feed reduction ratio of 6-1. This has been proven worldwide in most applications. In the case of a cone crusher the ration is closer to 8-1. Exceeding the crusher design limits is a common problem, and does not just affect wear on the plates, but the entire hydraulic system too, thus causing other severe issues to your machine.

I agree as well that the dust suppression should be with light spray nozzles and not a stream of water. Water also slows down the further process of screening.The only case where I have seen the benefit of adding water to material is before entering a VSI tertiary crusher, as this adds weight to the stone. Only if the stone is light and porous in weight, though it may still be abrasive... such as volcanic rock.

There are different types of jaw plates available that can have different depths and pitches to the corrugation. A jaw plate without corrugation will create a compaction event. You need corrugation but you can get a straight to a full belly style plate to help with your specific application. If this is what you meant by the profile then yes it could have an effect on jaw performance. There are also what they call "filled in end jaw dies" but should only be used for specific applications and only after consulting the crusher manufacture. And then it is only used on the stationary side as a rule. What I would recommend is talking to your crusher manufacture for specifics related to the types of plates available for your crusher. As with my company and others we have a teams of application specialist that would be happy to help and could offer a recommendation that could best fit your applications needs and help your crusher performance.

If usually your customer use Mn 18% with Cr 2%.The Materials work index that we crushed is 28, can you comment if we use a Jaw Plate with Mn 18 % with Cr 2% can reach a 500 hrs ?, last replacement of our Jaw Plate its only 150 hrs. this is our battle neck . As also mention in a comment about the different types of Jaw Plates, I think we have to find the correct design with this kind of materials we crush. We are in a river quarry, materials are mix .

The issues are very wellsummarized:including about the deleterious effects of fines and water on jaw life. Low-strength abrasive materials can cause standard manganese to wear surprisingly fast, as the wearing surface does not work-harden. With very abrasive materials, special 21-23% Mn alloys can help.

jaw crusher working principle

jaw crusher working principle

A sectional view of the single-toggle type of jaw crusher is shown below.In one respect, the working principle and application of this machine are similar to all types of rock crushers, the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the Dodge motion, being the resultant of the circular motion of the eccentric shaft at the top of the swing jaw. combined with the rocking action of the inclined toggle plate at the bottom of this jaw. The motion at the receiving opening is elliptical; at the discharge opening, it is a thin crescent, whose chord is inclined upwardly toward the stationary jaw. Thus, at all points in the crushing chamber, the motion has both, vertical and horizontal, components.

It will be noted that the motion is a rocking one. When the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire up-stroke. A reversal of this motion occurs during the downstroke of the eccentric.

The horizontal component of motion (throw) at the discharge point of the single-toggle jaw crusher is greater than the throw of the Dodge crusher at that point; in fact, it is about three-fourths that of Blake machines of similar short-side receiving-opening dimensions. The combination of favorable crushing angle, and nonchoking jaw plates, used in this machine, promotes a much freer action through the choke zone than that in the Dodge crusher. Capacities compare very favorably with comparable sizes of the Blake machine with non-choking plates, and permissible discharge settings are finer. A table of ratings is given.

The single-toggle type jaw crusher has been developed extensively. Because of its simplicity, lightweight, moderate cost, and good capacity, it has found quite a wide field of application in portable crushing rigs. It also fits into the small, single-stage mining operation much better than the slower Dodge type. Some years since this type was developed with very wide openings for reduction crushing applications, but it was not able to seriously challenge the gyratory in this field, especially when the high-speed modern versions of the latter type were introduced.

Due to the pronounced vertical components of motion in the single-toggle machine, it is obvious that a wiping action takes place during the closing strokes; either, the swing jaw must slip on the material, or the material must slip along the stationary jaw. It is inevitable that such action should result in accelerated wear of the jaw plates; consequently, the single-toggle crusher is not an economical machine for reducing highly abrasive, or very hard, tough rock. Moreover, the large motion at the receiving opening greatly accentuates shocks incidental to handling the latter class of material, and the full impact of these shocks must be absorbed by the bearings in the top of the swing jaw.

The single-toggle machine, like the Dodge type, is capable of making a high ratio-of-reduction, a faculty which enables it to perform a single-stage reduction of hand-loaded, mine run ore to a suitable ball mill, or rod mill, feed.

Within the limits of its capacity, and size of receiving openings, it is admirably suited for such operations. Small gravel plant operations are also suited to this type of crusher, although it should not be used where the gravel deposit contains extremely hard boulders. The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain.

As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particles weight and the friction between it and the crusher surfaces counteract this tendency. In particular, very hard rock tends to slip upward rather than break. Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. Smaller particles, which weigh less, and harder particles, which are more resistant to breakage, will tend to slip more. Anything that reduces friction, such as spray water or feed moisture, will promote slippage.

Leading is a technique for measuring the gap between fixed and moveable jaws. The procedure is performed while the crusher is running empty. A lead plug is lowered on a lanyard to the choke point, then removed and measured to find out how much thickness remains after the crusher has compressed it. This measures the closed side setting. The open side setting is equal to this measurement plus the throw of the mantle. The minimum safe closed side setting depends on:

Blake (Double Toggle) Originally the standard jaw crusher used for primary and secondary crushing of hard, tough abrasive rocks. Also for sticky feeds. Relatively coarse slabby product, with minimum fines.

Overhead Pivot (Double Toggle) Similar applications to Blake. Overhead pivot; reduces rubbing on crusher faces, reduces choking, allows higher speeds and therefore higher capacities. Energy efficiency higher because jaw and charge not lifted during cycle.

Overhead Eccentric (Single Toggle) Originally restricted to sampler sizes by structural limitations. Now in the same size of Blake which it has tended to supersede, because overhead eccentric encourages feed and discharge, allowing higher speeds and capacity, but with higher wear and more attrition breakage and slightly lower energy efficiency. In addition as compared to an equivalent double toggle, they are cheaper and take up less floor space.

Since the jaw crusher was pioneered by Eli Whitney Blake in the 2nd quarter of the 1800s, many have twisted the Patent and come up with other types of jaw crushers in hopes of crushing rocks and stones more effectively. Those other types of jaw crusher inventors having given birth to 3 groups:

Heavy-duty crushing applications of hard-to-break, high Work Index rocks do prefer double-toggle jaw crushers as they are heavier in fabrication. A double-toggle jaw crusher outweighs the single-toggle by a factor of 2X and well as costs more in capital for the same duty. To perform its trade-off evaluation, the engineering and design firm will analyze technical factors such as:

1. Proper selection of the jaws. 2. Proper feed gradation. 3. Controlled feed rate. 4. Sufficient feeder capacity and width. 5. Adequate crusher discharge area. 6. Discharge conveyor sized to convey maximum crusher capacity.

Although the image below is of a single-toggle, it illustrates the shims used to make minor setting changes are made to the crusher by adding or removing them in the small space between the crushers mainframe and the rea toggle block.

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher.

Crusher must be adjusted when empty and stopped. Never close crusher discharge opening to less than minimum opening. Closing crusher opening to less than recommended will reduce the capacity of crusher and cause premature failure of shaft and bearing assembly.

To compensate for wear on toggle plate, toggle seat, pitman toggle seat, and jaws additional shims must be inserted to maintain the same crusher opening. The setting adjustment system is designed to compensate for jaw plate wear and to change the CSS (closed side setting) of the jaw crusher. The setting adjustment system is built into the back frame end.

Here also the toggle is kept in place by a compression spring. Large CSS adjustments are made to the jaw crusher by modifying the length of the toggle. Again, shims allow for minor gap adjustments as they are inserted between the mainframe and the toggle block.

is done considering the maximum rock-lump or large stone expected to be crushed and also includes the TPH tonnage rate needing to be crushed. In sizing, we not that jaw crushers will only have around 75% availability and extra sizing should permit this downtime.

As a rule, the maximum stone-lump dimension need not exceed 80% of the jaw crushers gape. For intense, a 59 x 79 machine should not see rocks larger than 80 x 59/100 = 47 or 1.2 meters across. Miners being miners, it is a certainty during day-to-day operation, the crusher will see oversized ore but is should be fine and pass-thru if no bridging takes place.

It will be seen that the pitman (226) is suspended from an eccentric on the flywheel shaft and consequently moves up and down as the latter revolves, forcing the toggle plates outwards at each revolution. The seating (234) of the rear toggle plate (239) is fixed to the crusher frame; the bottom of the swing jaw (214) is therefore pushed forward each time the pitman rises, a tension rod (245) fitted with a spring (247) being used to bring it back as the pitman falls. Thus at each revolution of the flywheel the movable jaw crushes any lump of ore once against the stationary jaw (212) allowing it to fall as it swings back on the return half-stroke until eventually the pieces have been broken small enough to drop out. It follows that the size to which the ore is crushed.

The jaw crusher is not so efficient a machine as the gyratory crusher described in the next paragraph, the chief reason for this being that its crushing action is confined to the forward stroke of the jaw only, whereas the gyratory crusher does useful work during the whole of its revolution. In addition, the jaw crusher cannot be choke-fed, as can the other machine, with the result that it is difficult to keep it working at its full capacity that is, at maximum efficiency.

Tables 5 and 6 give particulars of different sizes of jaw crushers. The capacity figures are based on ore weighing 100 lb. per cubic foot; for a heavier ore, the figures should be increased in direct proportion to its weight in pounds per cubic foot.

The JAW crusher and the GYRATORY crusher have similarities that put them into the same class of crusher. They both have the same crushing speed, 100 to 200 R.P.M. They both break the ore by compression force. And lastly, they both are able to crush the same size of ore.

In spite of their similarities, each crusher design has its own limitations and advantages that differ from the other one. A Gyratory crusher can be fed from two sides and is able to handle ore that tends to slab. Its design allows a higher-speed motor with a higher reduction ratio between the motor and the crushing surface. This means a dollar saving in energy costs.

A Jaw crusher on the other hand requires an Ely wheel to store energy. The box frame construction of this type of crusher also allows it to handle tougher ore. This design restricts the feeding of the crusher to one side only.

The ore enters from the top and the swing jaw squeezes it against the stationary jaw until it breaks. The broken ore then falls through the crusher to be taken away by a conveyor that is under the crusher.Although the jaws do the work, the real heart of this crusher is the TOGGLE PLATES, the PITMAN, and the PLY WHEEL.

These jaw crushers are ideal forsmall properties and they are of the high capacity forced feed design.On this first Forced Feed Jaw Crusher, the mainframe and bumper are cast of special alloy iron and the initial cost is low. The frame is ribbed both vertically and horizontally to give maximum strength with minimum weight. The bumper is ruggedly constructed to withstand tremendous shock loads. Steel bumper can be furnished if desired. The side bearings are bronze; the bumper bearings are of the antifriction type.

This bearing arrangement adds both strength and ease of movement. The jaw plates and cheek plates are reversible and are of the best-grade manganese steel. The jaw opening is controlled by the position of an adjustable wedge block. The crusher is usually driven by a V-to-V belt drive, but it can be arranged for either V-to-flat or fiat belt drive. The 8x10 size utilizes a split frame and maybe packed for muleback transportation. Cast steel frames can be furnished to obtain maximum durability.

This second type of forced feed rock crusher is similar in design to the Type H listed above except for having a frame and bumper made of cast steel. This steel construction makes the unit lighter per unit of size and adds considerable strength. The bearings are all of the special design; they are bronze and will stand continuous service without any danger of failure. The jaw and cheek plates are manganese steel; and are completely reversible, thus adding to their wearing life. The jaw opening is controlled by the position of an adjustable wedge block. The crushers are usually driven by V-to-V but can be arranged for V-to-flat and belt drive. The 5x6 size and the 8x10 size can be made with sectionalized frame for muleback transportation. This crusher is ideal for strenuous conditions. Consider a multi jaw crusher.

Some jaw crushers are on-floor, some aboveground, and others underground. This in many countries, and crushing many kinds of ore. The Traylor Bulldog Jaw crusher has enjoyed world wide esteem as a hard-working, profit-producing, full-proof, and trouble-free breaker since the day of its introduction, nearly twenty years ago.

When the jaw crusher work, the movable jaw plats periodically moves back and forth to the stationary jaw plates, sometime close and sometimes away.
