Applied material: limestone, granite, cobble, dolomite, bluestone, iron ore, construction waste, glass, cement clinker, etc. Its structure: simple, compact size, light body weight, easy operation and maintenance.
After that, the materials smaller than the size of the screen hole are discharged through the gap, while materials of larger size are left on the screen plate to continue to be crushed and ground by a hammer, and finally discharged through the screen plate.
The hammer mill crusher is mainly PC series. With the development of the industry, the hammer crusher is constantly being improved. The heavy hammer crusher is its upgraded version, and the PCZ is the main series.
In terms of applicability and principle, there is almost no difference between them, except the difference is in the configuration position of the production line and the performance of the hammer.
The heavy hammer crusher is used for coarse crushing of ore, that is, the primary crushing process. The hammer crusher in the projects, especially large-scale crushing production lines, is often used together with heavy hammer crushers for medium or fine crushing.
The hammer head of the heavy hammer crusher is heavier than that of hammer crusher, generally higher than 20kg, so the crushing force of the material is greater, and the material that can be crushed per unit time is significantly higher than that of the general hammer crusher.
2 The humidity of processing raw materials. If the humidity of the raw materials is too high, there may be a bonding phenomenon when the hammer crusher works, and the particle size of the finished product will not be uniform.

JXSC hammer mill machine that hammerhead adopts a new technology cast which wear-resistant and impact-resistant. The airframe structure of the hammer mill is seal which solves the problems of dust pollution and dust leakage in the crushing workshop. And it is easy to maintain.
1. Hammerhead uses new cast technology which with wear-resistant and impact-resistant characteristic. 2. Can adjust the granularity size. 3. The seal structure that solves the problems of dust pollution and dust leakage in the crushing workshop. 4. The overall design of hammer crushing equipment has the advantages of beautiful appearance, compact structure, few wearing parts, convenient maintenance, etc.
Hammermill crusher mainly rely on impact energy to complete the crushing of materials. When the hammer mill rock crusher works, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly. The hammerhead with high speed turns impacts and tears the material lead to the materials are crushed.
At the same time, the material from the high-speed rotating hammerhead to the baffle and screen strip in the frame under the gravity effect. The material larger than the size of the screen hole remains on the screen plate and continues to be hit and ground by the Hammer. Then finally through the sieve plate discharge machine until the crusher material size discharge.
The advantages of the hammer: The ratio of crushing is large, generally is 10-25, high up to 50. High production capacity. uniform products. Less over-powder phenomenon. Simple structure, light equipment quality. Simple operation and maintenance, etc. The series hammer crusher products are suitable for crushing all kinds of medium hardness and brittle materials, such as limestone, coal, salt, gypsum, alum, brick, tile, coal gangue and so on. The compressive strength of the crushed material shall not exceed 150 MPA.
The series of crushers are mainly used in cement, coal preparation, power generation, building materials, and compound fertilizer industries. It can crush the raw materials of different sizes into uniform particles for the next working procedure. Reliable mechanical structure, high production efficiency, good applicability.
But the hammer crusher also has some disadvantages, such as the hammer and grate screen wear quickly. When crushing hard materials, they wear out faster. When crushing sticky wet materials, it is easy to plug the screen seam of the grate. Therefore, it is easy to cause shut down, so the moisture content of the material should not exceed 10 %. When milling hard objects, the hammer and lining plate have big wear. And the consumptive metal material is much, often needs to replace the wear-and-tear piece.

Many cement plants extract limestone by blasting, which often leads to oversized boulders containing a lot of clay and sand. The crusher therefore has to handle feed that contains larger blocks as well as some sticky materials. Our EV Hammer Impact Crusher is a proven, reliable and cost-effective impact crusher that help to overcome these crushing challenges.
In traditional hammer crushers with a top inlet, introducing large blocks in the feed can impede the action of the hammers and block the crusher. Our EV Hammer Impact Crusher, however, competently reduces quarry-size limestone boulders measuring up to 2.5 metres and weighing up to 5 tonnes to mill feed of 25 millimetres. This is a reduction ratio of 1:100 in a single operation. The EV Hammer Impact Crusher features a highly effective two-stage crushing process. Primary crushing takes place by impacting. Secondary crushing takes place by shearing and compression between the impact hammers and the breaker plate and between the hammers and the outlet grate. This ensures that even the smallest particles absorb energy and that no oversized particles leave the hammer impact crusher. The horizontal feed system can also tolerate coarse feed blocks because of its shock-absorbing inlet rollers.
The EV Hammer Impact Crushers throughput capacities range up to 2200 tonnes per hour (tph) with an outlet grate and 2500 tph without an outlet grate. Motor sizes are typically in the range of 500 - 2500 kW.
The hammer rows, which can vary depending on your crushing capacity needs, are arranged to provide complete coverage across the outlet grate. By arranging them in this way, the raw material can be crushed at multiple points increasing overall efficiency.
Adjustment of the spacing between the hammers, breaker plate and outlet grate can be optimised to compensate for hammer wear. Even when the hammers lose up to 30 percent of their original weight, the required product size curve is unaffected.
The adjustable outlet grate gives the EV Hammer Impact Crusher control of the maximum size of the product. The grate ensures a consistent flow to the conveyor and protects it against any sudden impact of material leaving the impact crusher at high speed. The grate also protects other nearby machinery from being damaged during operation.
The hold-up mechanism of the outlet grate generates a crushed product with a relatively high proportion of fines. In this way, more of the comminution work is moved from the less energy-efficient raw mill to the more energy-efficient hammer impact crusher.
The hammer rows are fitted in a staggered configuration to give complete coverage across the outlet grate. This provides several points for crushing of the raw materials, increasing the overall efficiency of the crusher.
The hammers are pivotally suspended from bolts and are symmetrically shaped. This reduces the full brunt from the contact between material and hammers, which protects the rotor and crusher housing. The hammers can easily be turned to reverse the leading and tracing edges for maximum service life.
Equipped with sturdy, replaceable grate bars supported by heavy cheeks, the adjustable outlet grate allows unique control of the mill feed size using hydraulic systems. This ensures a consistent flow to the conveyor. The outlet grate also serves as protection for the conveyor and other machinery such as reclaimers, sluices and mills, against operational upsets and mechanical damage.
A horizontal feed system incorporating one or two shock-absorbing inlet rollers helps to handle coarse feed blocks. The inlet rollers accurately control the feed to the hammer impact crusher and ensure a smooth and even flow of material. Whether one or two inlet rollers are used depends on the method of feeding the crusher.
Bolted-on, wear-resistant plates protect all exposed surfaces, including the adjustable breaker plates, from abrasive feed materials. The inlet rollers of the horizontal feed system consist of a cylinder and a concentric shaft driven by a separate motor. Rubber pads inserted between the shaft and the cylinder make the inlet rollers shock absorbent.
The hammer rotor assembly consists of a heavy-duty, forged shaft with a square cross section and is also fitted with rotor discs. The unique sandwich assembly of the discs is a robust construction, that helps prevent distortion and crack formation.
The top part of the EV Hammer Impact Crusher can be accessed by means of hydraulic cylinders. The supply package includes hydraulically-operated tools for fitting and dismantling of the heavy hammer bolts.
The hydraulic cylinders and tools are served by a mobile hydraulic power unit which can be stored in a separate room when not in use. A lifting yoke facilitates handling of the hammer rows when changing hammers. It also holds them in position when dismantling and fitting hammer bolts.

According to different features of different materials, HXJQ has improved the hammer crusher in its structure, application and function, and developed coal hammer crusher, glass hammer crusher, ceramic hammer crusher, cement hammer crusher, gypsum hammer crusher, limestone hammer crusher, quartz hammer crusher, etc.
1. Reversible type hammer crusher is often used for fine crushing process, and the finished products are uniform and fine. Reversible type hammer crusher has a large crushing ratio and can work stably.
2. Irreversible type hammer crusher is usually used for medium crushing process. Because its rotors can't rotate back and forth, it is also called as the impact hammer crusher. Irreversible type hammer crusher combines the advantages of hammer crusher and impact crusher and performs well in the crushing process. It is a technical and compact crushing machine with the features of low energy consumption, high capacity and low price.
Hammer crusher is used to crush materials with medium hardness and low corrosivity. The compressive strength of materials processed should be no more than 200Mpa, and water content should be lower than 15%.
Hammer crushing equipment is suitable for processing coal, gypsum, brick, tile, limestone, quartz, iron ore, granite, basalt, gangue, river pebble, calcite, wollastonite, bluestone, glass, cement, and other metal ores. Also, it is used to crush wood, paper, construction waste and recycled asbestos fiber, etc.
Besides, the hammer crushing machine can be not only applied in the crushing process and sand making process, but also can be adopted as the secondary crushing equipment to replace cone crusher and impact crusher, and used in the beneficiation processing line.
Hammer is made of high-quality manganese steels and treated by strict heat processing and then it becomes single austenite. After the process, the service life has been prolonged 4 times than traditional hammer crushing machines and working efficiency has been improved more than 30%.
The crushing process of hammer crushing machine is that the power drives the hammer to crush materials, and the crushed materials are impacted on the counterattack plate, and then the materials rebounded by the counterattack plate hit the materials impacted by the hammerhead.
Hammer crusher mainly relies on the impact force to complete the crushing. When the hammer crusher works, the motor drives the rotor in high-speed rotation. The materials are sent into the crusher chamber evenly and after a high-speed impact of hammer, the material is crushed into a smaller size.
The material larger than the sieve mesh is remained in the screening plate for further impacting and grinding. The material smaller than the sieve mesh is discharged from the hammer crushing machine to the material piles.
HXJQ as one of the professional hammer crusher manufacturers in China, mainly produces jaw crusher, cone crusher, hammer crusher, impact crusher, sand making machine, vibrating screen, feeding machine, sand washing machine and supporting equipment such as dust collector and conveyors, etc.
HXJQ undertakes various construction projects of large-capacity sand and aggregate production lines and serves from the equipment design, manufacturing, project survey, production line design, construction, equipment installation and debugging to after-sales service.
Compound Cone Crusher, widely used in the industries of metallurgy, building material, road construction, chemical engineering & silicate, is suitable for crushing all kinds of ores and rocks with medium or above hardness. Compound Cone Crusher is divided into standard type and short-head type. Generally speaking, the standard type has big feeding granularity and relatively coarse discharging granularity, and the short-head type has steep crushing cone and small feeding granularity which is conducive to producing fine particle materials, for this reason,the standard type compound cone crusher is generally used for coarse and medium crushing and the short-headed type compound cone crusher is generally used for medium and fine crushing.
It has unique hydraulic clearing system,hydraulic opening adjusting function,easy for changing movable and fixed plate,decreasing management and maintenance cost. It is widely used for medium and fine crushing of granite,basalt,cobble,cobblestone,iron ore etc, which is well received by customers.
Cone crusher when working, the motor drives the eccentric bearing via the spring coupling, the transmission shaft and a couple of cone gear wheels. The crushing cone axis is forced to swing by the eccentric bearing bushing, which makes the mantle sometimes close to the bowl liner, and sometimes far away from the bowl liner. The raw materials are pressed, impacted and finally crushed in the copper.

A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the material gets smaller as it moves down through the wear liner as the opening in the cavity gets tighter. The crushed material is discharged at the bottom of the machine after they pass through the cavity.
A Cone Crusher will deliver a 4:1 to 6:1 reduction ratio. As we set the closed side setting tighter to create a finer output, we also reduce the volume or throughput capacity of the machine. Generally speaking, multiplying the closed side setting by two is a good guide to the top size of the gradation exiting the machine.
The technology that makes a MSP Cone Crusher outperform competitive cones on the market is the combination of all of the factors of performance i.e. balanced eccentric, higher speeds, fulcrum point position, and stroke. By using sound engineering with years of field testing a truly tried and tested new Cone Crusher has emerged.
A balanced eccentric coupled with a fulcrum point ideally placed over the crushing chamber yields highly effective compression crushing. This allows higher eccentric speeds to maximize performance without disruptive forces. The eccentric stroke is designed to work with the eccentric speed and fulcrum position to produce higher yields and minimize recirculating loads. The torque and resultant crushing forces are as effective as virtually any Cone Crusher on the market.
Spiral bevel gears provide the turning force to the eccentric. The spiral gear is mounted on a sturdy countershaft of the Cone Crusher, which rides in bronze bushings. The gears are precision cut for quiet operation. Misalignment problems are eliminated.
The MSP Cone Crusher features one of the largest volume displacements by a crusher head. When there is a large volume of material displaced this way, it means that more material is crushed in each cycle, more material can be fed to fill the larger void left when the crushing head recedes, and more material flows through the crusher due to the larger throughput and gyrating cycles allowing material to drop further. The benefits of high efficiency, greater crushing force and high capacity coupled with the durability the market expects are the reasons why this design is the best way to increase your productivity and profitability.
Sleeve bearings make removal and installation of the MSP Cone Crusher head and main shaft simple. The tapered main shaft fits into a large opening at the upper end of the tapered eccentric bushing. The shaft does not require precise alignment. It can be inserted from a vertical position and will self-align.
With the MSP Cone Crushers automatic hydraulic overload relief system, the crusher immediately opens in the event of an overload. This action reduces the crushing pressure, allowing the obstruction to pass through the chamber. After the chamber has been cleared, the hydraulic control system automatically returns the crusher to its original setting. Shock loads on the crusher are reduced for longer component life.
MSP Cone Crushers are built to make your operations run more smoothly and easily. Its simple and easy to read control panel provides you with the necessary information to properly run your crusher. For example, the MSP Cone Crusher shows you the exact cone setting to allow the operator to stay on top of a critical set point.
To enhance your Cone Crusher's life and maintain optimal crushing capacities, an automatic liner change reminder is included for your convenience. When the new mantle and liners are installed, the automated reminder is reset. As the crusher operates, the system will track production capacities and calculate the liner wear rate. When the cone liners reach the maximum wear point, it sends a flashing reminder to 'change cone' on the cone setting meter. After the wear parts are changed, simply reset the automated reminder system and continue efficient, reliable crushing.
The MSP Cone Crushers are built heavier than most competitive Cone Crushers. The extra weight means lower stress on the machine, which results in longer operational life. There is no question that the proper use of mass makes for more durable crushers. Additionally, a broad array of manganese liners is offered for each size MSP Cone. A unique and patented feature allows the Liners to fit without the use of any backing material. Improved Chamber matching with crusher feeds virtually eliminates any trial and error.
All these factors combine to give producers more effective compression crushing. This reduces liner wear, which reduces wear cost and allows higher yields, resulting in decreased overall cost per ton of finished product.
In the Symons principle, which is utilized by the MSP Cone Crusher, each cycle is timed so that the feed material and the upward thrust of the crushing head meet at the moment of maximum impact. The optimum speed of gyration and the large eccentric throw produce two important results: 1) the rapidly closing head catches the falling feed material and delivers the extremely high crushing force and 2) on the other side of the chamber the rapidly receding head allows material to fall freely to the next point of impact or exit the chamber. The combination of superior crushing force and free flow of material in the MSP Cone Crusher results in production levels that are unsurpassed and means lower power consumption per ton.
Ten years of testing went into the final combination of speed, stroke, and head angle to deliver the most efficient use of power. Greater efficiency delivers lower power consumption, reduced cost per ton, less maintenance and higher profits.
The power input imparted by the driven eccentric results in a bearing force in opposition to the crushing force at a point on the lower portion of the main shaft. The bearing force as it is transmitted to the main shaft provides the required moment to crush the rock. The distance between the bearing force and the fulcrum point is called the force arm. The longer the force arm, the greater the momentum, which produces a greater crushing force.
Crushing loads are distributed over a large spherical bearing. The socket liner keeps full contact with the crushing head ball and carries all of the vertical component and part of the horizontal. The long force arm, represented by the main shaft, reduces the load transmitted through the eccentric bushing.
Capacities and product gradations produced by Cone Crushers are affected by the method of feeding, characteristics of the material fed, speed of the machine, power applied, and other factors. Hardness, compressive strength, mineral content, grain structure, plasticity, size and shape of feed particles, moisture content, and other characteristics of the material also affect production capacities and gradations. Gradations and capacities are most often based on a typical, well-graded choke feed to the crusher. Well-graded feed is considered to be 90% to 100% passing the closed side feed opening, 40% to 60% passing the midpoint of the crushing chamber on the closed side (average of the closed side feed opening and closed side setting), and 0 to 10% passing the closed side setting. Choke feed is considered to be material located 360 degrees around the crushing head and approximately 6 above the mantle nut. Maximum feed size is the average of the open side feed opening and closed side feed opening.
Minimum closed side setting may vary depending on crushing conditions, the compressive strength of the material being crushed, and stage of reduction. The actual minimum closed side setting is that setting just before the bowl assembly lifts minutely against the factory recommended pressurized hydraulicrelief system.
Overall, industry acceptance of the Symons principle and performance, the McLanahan Cone Crusher works to deliver lower recirculating loads at higher tonnage rates with lower maintenance costs by combining:
A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 34 closed side setting, the maximum feed would be 6 x 34 or 4.5 inches. Reduction ratios of 8:1 may be possible in certain coarse crushing applications. Fine liner configurations typically have reduction ratios of 4:1 to 6:1.
The difference between the volume displaced by the crushing head when it is fully closed and fully open is called the displacement volume. A large displacement volume results in greater capacity because:
In order to maintain the maximum levels of capacity, gradation, and cubical product, a Cone Crusher must be choke-fed at all times. The best way to keep a choke-feed to the ConeCrusher is with a surge bin (or hopper) and feeder that are located prior to the crusher. Choke-feeding is almost impossible to achieve without a hopper and feeder.
There are a number of different criteria to consider when selecting the right chambers for your crushing needs. However, the one that must always be considered isthat you have a well-graded feed to the chamber. A well-graded feed is generally thought to be 90 to 100% passing the closed-side feed opening, 40 to 60% passing the midpoint, and 0 to 10% passing the closed-side setting.
One thing you should never do is place a new concave liner in a crusher with a worn mantleor place a new mantle in a crusher with a concave liner. Why? If you have properly selected the replacement component, you will change the complete profile of the Cone Crusher by mating new and worn components. The receiving opening will tend to close down, restricting the feed from entering the chamber and causing a reduction in tons per hour.
If the liner is wearing evenly throughout the chamber, you should consider changing out the manganese when it has worn down to about 1" (2.5 cm) thick at the bottom. At about 3/4" to 5/8" (1.9 to 1.6 cm) thick, the manganese will crack, causing the backing material to begin to disintegrate. This, in turn, will cause the liners to break loose. If this should happen, continued operation could destroy the seat on the support bowl or the head of the Cone Crusher.
McLanahan Symons Principle (MSP) Cone Crushers utilize a combination of improved factors of performance, which are enhanced by the Symons Principle of crushing, as well as the latest hydraulic features and electrical features that create a modern, efficient, reliable and durable Cone Crusher that ultimately leads to a faster ROI. MSP Cone Crushers are designed to make your operation run more smoothly and easily, as well as ensuring lower operating costs and minimal downtime so that MSP Cone Crushers are more frequently fully operational and processing optimal amounts of material.
Efficiency can be defined by the ratio of the work done by a machine to the energy supplied to it. To apply what this means to your crusher, in your reduction process you are producing exactly the sizes your market is demanding. In the past, quarries produced a range of single-size aggregate products up to 40 mm in size. However, the trend for highly specified aggregate has meant that products have become increasingly finer. Currently, many quarries do not produce significant quantities of aggregate coarser than 20 mm; it is not unusual for material coarser than 10 mm to be stockpiled for further crushing.
Hammer crusher and jaw crusher are common crushing equipment in the mine/building materials industry. They have large feed inlet and high crushing efficiency and are mainly used for coarse crushing of various ore materials. But they are different in many parts, which is better? Table of Contents 1. Different Appearance and Working Principle2. Different for Applicable Materials3. Different Discharging Adjustment Methods4. Different Structure and Wearing Parts5. Different Configuration of Production Line6. Different Application of Aggregate Line7. Which is Better, Hammer Crusher or Jaw Crusher
The appearance and working principle of the 2 crushers are different. The jaw crusher is of the curved dynamic extrusion type, and the materials are crushed in the crushing cavity composed of the moving jaw and the fixed jaw. The hammer crusher is mainly broken by the impact, shear and tear of the rotating hammer head, the mutual impact between materials and the counterattack of the lining plate.
Hammer crusher is mainly used to crush ores with low hardness, and its compressive strength is generally lower than 200Mpa, such as limestone, bluestone, coal gangue, etc. When crushing hard materials, the hammer head is seriously worn and the cost of frequent replacement is high.
The adjustment of the discharging granularity of the hammer crusher is realized by changing the bottom sieve plate. There are three adjustment modes of jaw crusher: base plate adjustment, wedge adjustment and hydraulic cylinder.
Hammer Crusher is rarely used in aggregate production line. Although the process is simple, the yield is low, it is easy to be over crushed, and there are many powdery materials. Moreover, the finished aggregate may have microcracks, low compressive strength, which will affect the quality of aggregate, sales and price. Therefore, it is often used as auxiliary sand making machine.
The main advantage of hammer crusher is that the ore with low hardness can be formed in one time. For the production line with output < 300t/h, a single hammer crusher can replace a jaw crusehr + a impact crusehr.
The main advantages of jaw crusehr are simple structure, convenient maintenance, high wear resistance, high cost performance, suitable for all kinds of hard ores. However, due to the high content of needle and flake aggregates in the discharge, it is necessary to cooperate with impact crusher for shaping.
