Jaw crusher and hammer crusher are the more common types of crushers we use when crushing stones. We often have friends who call to ask if you want a single hammer crusher, but dont want to use the jaw crush. Can it work? To clarify this problem, we must first understand the five major differences between jaw breaking and hammer breaking.
After understanding the 5 major differences between jaw breaking and hammer breaking, we must choose equipment according to our own needs, and we must understand our material properties and production requirements (for example, whether the requirements for the finished material are high), so as to configure the most The best production line equipment avoids subsequent production problems like the ones mentioned above.
Luoyang Dahua Heavy Machinery Co., Ltd. is located in luoyang, the ancient capital of A millennium, mainly engaged in all kinds of crushing, screening, grinding, washing, feeding, conveying, environmental protection, dust removal and other equipment research and development and production manufacturing.
Glass is not only a necessary material in construction and people's daily life, but also the important material to science and technology. Meanwhile, our life inevitably produces a large amount of glass waste which will seriously affect our life.
The recycling glass is more than 5 million tons per year in America and the producing glass waste in China is more than 10 million tons per year. All the glass wastes are valuable treasures to us if we treat them reasonably. Recycling and reusing glass wastes will not only bring us economic benefits, but also bring benefits to our environment.
Glass hammer crusher is one of the hammer crushers produced by HXJQ Mining Machinery. Aimed at the features of glass, HXJQ has specially developed the hammer crusher for glass. This crusher is mainly processing glass bottles (such as beer bottle), glass pot, glass wastes, automotive glass and glassware, etc.
Glass is one of the inorganic nonmetallic materials, which is made of multiple inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, quartz stone, feldspar, sodium carbonate, etc.). The chemical components of common glass are Na2SiO3, CaSiO3, SiO2, Na2OCaO6SiO2, etc.
Because the main components of glass are silicon dioxide and other oxides, the Moh's hardness of glass is about 6.5. Theoretically, the compressive strength of glass is between 700 and 1000 MPa, which is hard to crush.
However, the glass is very fragile, and the fragility of glass is in the range of 1300 to 1500 (relatively speaking, the steel's fragility is between 400 to 600, and the concrete's fragility is in the range of 4200 to 9350). According to this feature, glass can be laminated crushing by hammer crusher to achieve a good crushing effect.
Its wear resistance, pressure resistance, impact resistance and performance are improved during the operation. It is safer and more stable, has a low problem rate, high operating efficiency, and long service life, which can provide customers with very large economic benefits.
The hammer crusher can be used for both dry and wet crushing, and some recycled glass products inevitably contain some water. For this phenomenon, the glass hammer crusher sets the lower part of the counterattack plate to an open mode without a sieve. The material passes more, and the material will not block when the humidity is high.
The inlet port is large, the disposal amount is large, the processing capacity is high, and the inlet and outlet ports can be adjusted correctly according to the actual production requirements of the customer, and the adjustment range is large, the discharge granularity can be adjusted, and the use of the agitation is strong.
The bulk glass falls vertically from the upper part of the machine into the impeller of high-speed rotation, and is broken by the impact of the hammer head of high-speed rotation. The broken material obtains kinetic energy from the hammer head, and rushes from the high-speed to the baffle inside the frame.
At the same time, the glass collides with each other and is crushed several times. The material smaller than the gap between the screen meshes is discharged from the gap, and the larger material is crushed again by the impact, grinding and extrusion of the hammer head.
The crushed glass is extruded from the gap by the hammer head to form a closed circuit for multiple cycles, and is controlled by the screening device to achieve the required finished product particle size, thereby obtaining a product of the desired particle size.

Hammer Crusher ManufacturerJXSC manufactures various industrial hammer mills, hammer crushers and laboratory use small hammer mills to accomplish your size reduction needs. Our rugged hammer mills employ a rain of continual, high-speed hammer blows to impact crush, grind or shred of a diverse range of materials. Other rock crusher machines like roll crusher, impact crusher, jaw crusher, cone crusher, etc.Common Faults Solutions Hammer crusher in cement plantImpact hammer crusher (cement crusher) combines the advantages of ring hammer crusher, impact crusher, optimizes the grinding chamber, obtains a better fine crushing effect. Coal crusher hammervaried in different capacity requirements, the coal crusher hammer type generally have small capacity hammer crusher (5-55m/h) and the heavy hammer crusher (100-3200t/h).
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.

Coal hammer crusher is important equipment for crushing large raw coal. Its stable operation plays an important role in ensuring the raw coal conveying efficiency of the underground coal mine. We can put forward the corresponding solutions via analyzing the main fault sources and common faults of coal hammer mill crushers. Then improve the hammer coal mill crushers operation reliability, reduce the maintenance difficulty, and make sure the smooth progress of coal mining.
According to the working principle, coal crusher can be divided into two types: hammer crusher and jaw crusher. The hammer mill crushers have large processing capacity that max capacity is 4000tph. So the coal plant mainly uses hammer crushers to crushing raw coal. The power of the hammer crusher general is 90 ~ 400kw, which mainly depends on the rotating parts to drive the hammer up. Then crush the lump coal to the particle size which is easy to transport by the impact force of the hammer falling.
As important equipment of the underground coal mine transportation system, a coal hammer crusher is usually installed in the middle of the climbing section. The large piece of raw coal is transported to the transfer machine by the scraper conveyor and then guided into the hammer crusher by the transfer machine. The coal is crushed into small pieces by a hammer coal crusher and then transported to the ground coal yard.
The coal hammer mill crusher is composed of a bottom groove, crushing frame, hammer shaft, driving and adjusting device, and lubricating system. It has no transshipment function which needs after connecting the crushing bottom groove and connecting slot. Then uses the transshipment machine. The hammer impact crusher frame body is located on the upper part of the bottom groove and installs a crushing hammer shaft in the middle of the frame body. The mechanism is that the hammer shaft is lifted to a certain height through the transmission device which increases the gravitational potential energy. After falling, the hammerhead impacts and squeezes the raw coal at the bottom trough, crushing it to smaller particle sizes. The small coal particle is convenient for continuous conveying by the transfer machine.
According to the power of the equipment, the underground coal hammer crusher adopts two different transmission forms: pulley and retarder. In general, the belt pulley transmission is only used for power below 250kw. The power greater than 250kw is through the reducer.
Analyze fault for the large-scale, high-power hammer mill crusher, it cant diagnose specific faults. If the equipment fault is considered to be caused by the damage of a single component, the diagnosis is too one-sided. The test results may be biased, and the subsequent maintenance of the equipment may not achieve the desired repair effect. Therefore, the failure of a high-power hammer crusher should be considered from various factors, such as the design, processing, installation, commissioning and use.
The design should ensure the stability of the structure and the good dynamic characteristics of the equipment. The unreasonable mechanical structure will lead to the local stress concentration and affect the dynamic characteristics of the equipment. Then they may lead to forced vibration or self-excited vibration and other undesirable phenomena. In addition, the common design and manufacture defects include working speed and the material of the spare part can not meet the design requirements, machining accuracy is too low, poor moving cone balance performance, etc.
The hammer crusher installation, commissioning and maintenance stage may occur crusher parts installation dislocation. The transmission system with the shafting and installation location is not appropriate. The overall equipment geometric parameter adjustment is not good. The installation position of the dynamic cone is not reasonable. All the problems may lead to the equipment large load and poor stability in operation.
In the process of man-made operation, the equipment abnormal opening, closed and adjusted speed improperly. The equipment operated beyond the designed working condition for a long time. Lack of maintenance. Lubrication between the components was insufficient. These also cause the failure of the hammer crusher.
The coal hammer crusher operates for a long time, the parts are easy to wear and deformation. Individual parts may be shaken off, crack or even damage. The dynamic cone changes, spare parts will also be affected by the external environment caused by pitting or corrosion. Or with other parts wear each other. Or affected by vibration which causes uneven settlement of the ground where the equipment is located. At the same time, the increase of clearance between some spare parts, losing fit surface and lowering of fit surface friction will affect the normal work of the hammer mill.
The vibration and the movement of the dynamic cone in the operation of the hammer crusher will cause the dynamic cone ware. Then lead to the eccentricity of the center of gravity of the dynamic cone and the unbalance of the dynamic cone. The problems caused by the unbalance of the movable cone are as follows:
In the rotor system which connects with coupler, misalignment between the two rotors will cause the coupler to deflect. The bearing affected will shorten the service life, affect the stability of oil film, the operation is not smooth. We should increase the monitoring of rotor misalignment faults and focus on the detection of vibration amplitude and phase stability.
The rotor system is affected by factors such as misalignment of the rotor, bending of the shaft, loosening of the foundation, wear of the bearing, improper assembly, etc. It will rub-impact with bearings. Although the torque of the rotor can be balanced when the equipment is running, the speed is greatly affected. The rotor system is unstable, and the overall stability of the equipment decreases.
The main performance: one is the rotor system vibration, the other is the impact of rub-impact on the rotor itself. The combination of the two results in more complex adverse reactions, such as phase reverse displacement and axial trajectory diffusion or turbulence. In the design stage, in order to ensure the stability of the equipment, the gap between the rotating parts and the adjacent parts is relatively small, and the probability of the rub-impact phenomenon is more easily increased.
Oil Whirl is a phenomenon that the rotor of the transmission system moves the wedge oil film around the center of the bearing bush according to the average velocity of oil due to vibration and rotation fluctuation. The main characteristics are the smooth phase. It is obviously affected by lubricating oil characteristics. The trajectory presents a double ring ellipse. The subharmonic generated by the vibration will change with the increase of the rotational speed.
Hammer crusher is rotating vibration equipment. The foundation and fixed foundation bolt vibration during the crusher machine operating. It is easy to cause the bolt loose. At the same time, the bearing pedestal will be loose because of vibration. Vibration amplitude is large, mainly acting in the vertical direction. In order to determine the foundation and bearing pedestal looseness, the vertical vibration signals are detected and compared with the vibration signals of crusher and foundation bolt. If the foundation and the bearing seat are looser, there will be a big difference between the two vibration signals, which should be handled in time to avoid accidents.
The coal hammer crusher is the key equipment for crushing large raw coal in the underground coal. The machine is an important part of the raw coal transportation system. The common problems are design Defects, installation, debugging and maintenance problems, parts wear and deformation, movable cone unbalance, rotor rub-impact, shaft misalignment, etc.

We have compared the pros and cons of many rock crushing equipment, and have received feedback from many users. So, we made this post to help you understand the difference between cone crusher and hammer crusher.
Indeed, the hammer crusher can break materials at one time without secondary crushing, but it is more common in small and medium-sized production lines and the requirements for the final particle size are not high.
You should properly note that hammer crusher can not and should not use to handle materials with high hardness, otherwise, the hammerhead will wear out quickly and you may need frequent repair and change the wearing parts, this will increase your costs a lot.
Although the process is simple, it has many shortages, for example, the yield is low, and the final aggregate product may easily be crushed or product micro cracks. This poor quality will affect sales and prices, so the hammer crusher now is often used as an auxiliary sand making equipment.
Although the initial purchase cost is not high, the replacement of the wearing parts such as hammerheads in the later stage is also a large cost, especially for crushing medium-hard and above materials.
Hammer crusher and cone crusher are both classic equipment in aggregate crushing and are both widely used. This article briefly analyzes the difference between those two types of crushing machines in 6 factors, and we hope it can help you.
In addition, it should be noted that what we call hammer crusher is a product in the traditional sense, because in many regions, small and medium-sized production lines still use this type of equipment because the crushing ratio is large and the price is low.

The hammer crusher mainly rely on the impact action to crush raw materials into small size. Thus, it is a necessary equipment for many industries, especially pharmaceutical, feed, food, coating, chemical industry. Here, the hammer crusher from SEEC is a specialized crushing equipment for fertilizer production. Especially for large scale fertilizer production, most customers choose to use this kind crush machine. When the raw materials enter in this machine, they can be crushed for many times. Until the materials are smaller than the clearance of the sieve bar they will be discharged from the clearance and finish crushing process.
This crush machine is the ideal crushing equipment to crush the corn stalk, straw, peanut husk, bean stalk, cotton wastes, branches, leaves, sawdust, etc. If the compost material contains too much water, the crushed organic material can help absorb the excess water to adjust the humidity of raw materials. So, if you want to make high quality fertilizer, this crusher is necessary to you. Besides, this straw crusher is easy to operate and would not occupy too much space in fertilizer plant.
Chain crusher is suitable to crushing nubby materials in compound fertilizer making process. Meanwhile, it is also suitable for the crushing of returned materials in fertilizer production. Its installation form is divided into vertical and horizontal. For vertical chain crusher, it has single rotor. While horizontal type it has double rotors.
Urea crusher is used to crush all kinds of single chemical fertilizers with water content less than 40%, especially for materials with high hardness. Before you use this crusher, you should place this machine in a certain position in the workshop, and it can be used when connected to the power supply. The fineness of the crusher is controlled by the spacing between two rollers, the smaller the spacing is, the finer the fineness will be.
Cage fertilizer crusher belongs to medium-sized horizontal fertilizer crusher machine. It is designed according to the impact action to crush materials. When it is working, the inside and outside cages rotate in the opposite direction with high speed, then the material is crushed from inside to outside by the impact of the cage. The crusher has the advantages of simple structure, high crushing efficiency, good sealing performance, stable operation, easy cleaning, convenient maintenance and so on.
If you are doing large scale fertilizer production, SEEC recommend you to use the hammer crusher in your fertilizer production line. This machine is the first choice for large scale fertilizer business. When this crusher is working, the motor drives the rotate at high speed, then the organic material goes into the crusher chamber evenly. This crushing machine has high crushing efficiency and high production capacity. Whats more, it is also a durable crushing equipment.
Zhengzhou Shunxin Engineering Equipment Co., Ltd. mainly produces fertilizer equipment. The company is an environmental protection high-tech enterprise specializing in researching and manufacturing organic fertilizer and compound fertilizer equipment. The company was founded in 2005. The factory is located in Xingyang, Zhengzhou, with an area of 60 acres and a standardized heavy industrial factory building of 40,000 square meters.
Impact crusher and hammer crusher both use impact principle to crush materials, and the finished material has excellent particle shape. From the appearance, impact crusher and hammer crusher are similar, but they are different in many aspects, so which is better?
Hammer crusher is divided into single rotor and double rotor. The main body is composed of box, rotor, hammer head, impact lining plate, sieve plate, etc. it can directly crush the material with the maximum particle size of 600-1800 mm to 25mm or below.
In contrast, the crushing chamber of hammer crusher is smaller, the impact effect cannot be fully exerted, and the impact crusher is of multi chamber crushing structure, so the crushing is more sufficient.
The plate hammer and rotor of the impact crusher are rigidly connected. The inertia of the whole rotor is used to impact the material (free crushing, impact crushing, milling crushing), so that materials can not only be crushed but also obtain a larger speed and kinetic energy. The plate hammer is used to smash the input material from the bottom to up and throw it onto the upper impact plate.
The hammer head of the hammer crusher is used to crush the material (free crushing, impact crushing), and the speed and kinetic energy obtained by the material are limited. The hammer head striking materials along the material falling direction, with small crushing effect.
The wear of impact crusher plate hammer often occurs on the side that facing the materials, and its metal utilization rate can be as high as 45% 48%. When crushing limestone, the plate hammer of impact crusher is not seriously worn, but when crushing granite (with high hardness, it can be broken by cone crusher), the plate hammer needs to be replaced constantly.
The hammer head of hammer crusher is in a suspended state, and the wear occurs at the top, front, back and side. Compared with plate hammer, the hammer head is more seriously worn, the metal utilization rate of hammer head is about 35%, and the rotor may also be worn.
The feeding chute and the counterattack plate of the impact crusher can be equipped with heating device to prevent the material from binding, so the material with large water content can be crushed and the blocking is not easy to occur.
The impact crusher is not easy to block the material. First, it can be equipped with heating device to prevent the material from blocking due to sticking. Second, there is no grate bar at the bottom. The product size is determined by the gap between the impact plate and the plate hammer. Therefore, when handling the material with too much water content, it can avoid blocking the grate bar when crushing the wet material.
Both of them are suitable for crushing medium and hard materials, but the impact crusher is mostly used as the secondary crushing equipment. While the hammer crusher is mostly used in the cement production line, as the limestone raw material crushing equipment, or as the primary crushing equipment in the sand aggregate plant.
The compressive strength of materials suitable for hammer crusher is within 200MPa, such as coal gangue and limestone, while the compressive strength of materials suitable for impact crusher is within 350Mpa, such as gypsum, coal gangue, limestone, river pebble, sandstone, quartzite, etc. the application scope of impact crusher is wider.
In the market, the frame part of the advanced impact crusher is a three-part structure, which only needs to open the shell at the back of the crusher to replace the plate hammer, impact plate, lining plate and other maintenance operations. Moreover, there are few varieties of vulnerable parts, which is convenient for the purchase and management of spare parts.Get in Touch with Mechanic
