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.

Jaw crusher can adopt advanced manufacturing technique and high-end materials, so it has a wide range of adaptability to stone materials properties.

Cone crusher is quite excellent in hard stone material crushing process and the final product has good sharp. As we all know, cone crusher is mainly used in the second crushing in the stone crushing process. The performance advantages of cone crusher closely related with the structure and working principle of the equipment. Compared to jaw crusher, with grease seal and upstage sealing element imported from Japan, cone crusher can provide sturdy guarantee for long-playing stable operation of machine. Cone crusher Chinese equipment manufacturer provided is a machine used for breaking big stone into minor rocks, which has made great contributions on medium and fine crushing of all kinds of stone with compressive strength under 350Mpa. According to our market survey, the characteristics of cone crusher in China are simple structure, steady performance, easy maintenance, high productivity, high efficiency, high quality, etc.The fine processing of cone crusher in stone crushing process has becomes a key factor which can promote city construction process of China.

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.

Applied materials: pebble, calcite, granite, quartz, concrete, dolomite, bluestone, iron ore, limestone, coal gangue, construction waste, ferrosilicon, basalt, sandstone, rocks, ore, glass, cement clinker and some metal.

Jaw crusher, invented by Whitney Blake in 1858, is a primary stone crushing machine for reducing minerals or stones into smaller sizes. It is a must-have machine in wide range of fields like mining, quarrying, and construction industries.

The movable jaw moving from side to side is hung on the mandrel. When the eccentric shaft is turning, its connecting rod moves up and down, which also drives the two toggle plates to do the same movement. Then the moveable jaw moves from side to side to realize crushing and unloading.

Although the movable jaw bears great broken counter-force and the eccentric shaft and the connecting rod bears little stress, industrial enterprises usually make large and middle size machine to crush hard materials. Additionally, the moving track of the movable jaw is an arc with the mandrel as its center.

The circular arc radius equals the distance from the point to the axis with the upper arc being smaller and the lower arc bigger. The crushing efficiency of the jaw crusher is quite high and the crushing ratio is 3-6.

We all know that jaw plate is the most easily worn parts among various of parts installed in jaw crusher. Therefore, in order to use the machine efficiently, the jaw plate should be checked and replaced regularly.
