The hammer crusher is a crusher that directly crushes materials with a maximum particle size of 600-1800 mm to 25 or less. Hammer crusher is a kind of equipment for crushing materials in the form of impact. It is divided into the single rotor and double rotor. This hammer mill crusher can save you cost and time because of shaping materials one time.
What is a hammer crusher machine? It is a kind of mining crusher for crushing limestone, coal, dolomite, brick, tile, gangue and other materials and sometimes it is also called coal hammer crusher. It is a kind of equipment which could directly crush the materials with the largest particle size like 600-1800mm into less than 25mm. Hammer crusher is widely used in cement, chemical, electricity, metallurgy and other industries to conduct middle and fine crushing to middle hard materials like limestone, slag, coke, coal, and others.
Heavy hammer crusher is used for crushing all kinds of hard and weak abrasive materials. The compressive strength of the material should not exceed 100MPa and the moisture content should be less than 15%. The materials crushed by ring hammer crusher are coal, salt, chalk, gypsum, brick, limestone, etc. It is also used to break fiber structure, strong elasticity, and toughness of broken wood, paper or broken asbestos cement waste to recover asbestos fiber and so on. In addition, heavy hammer crusher can be used not only in a sand production line but also in the mineral processing line.
The heavy duty hammers mainly rely on the impact energy to complete the crushing material operation. When the hammer crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. The high-speed rotary hammer impacts and shears materials to be broken.

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.

Hammer Crusher Partscrushing chamber, rotor shaft, frame, impact hammer, grate bars, motor, flywheel, grate, pallets and lining, dust seal, overload protection device. Hammer Crusher Working principleMaterial are fed into the hammer crusher, that is subject to rotation, high-speed impact and collision are broken. Qualified crushed ore is discharged through the grate, the larger size materials continue to be crushed and shattered until they reached the required 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).
Impact crusher involves the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor. There are two types: horizontal shaft impactor and vertical shaft impact crusher.
Hammer crusher is equipment which in the form of impact crushing materials. The divided into the single rotor and double rotor two forms. The maximum particle size of 600-1800 mm of material will crush to 25 or less than 25 mm directly. Hammermill is suitable for crushing medium hardness materials. Such as medium crushing and finely chopped working of limestone, slag, coke, coal, and other materials.
1.1 The crushing ratio of the impact stone crushers can reach more than 50. And the particle shape of the finished product is good. Under the impact action, the broken material is often along its most vulnerable layer surface. At this selective crushing method, the material size is even, the material is the cubic shape. And the fine powder and the dust content is low. The high-grade Highway skid-proof pavement uses it as the final breaking equipment to produce usually.
2.1 the frame of the impact-crushers is a three-part structure. Then it is only necessary to open the back shell of the crusher to replace the Hammer, the impact plate, the lining plate, and other maintenance operations. And the interchangeability of the parts of the machine is strong. The variety of fragile parts is less, which is convenient for the purchase and manage.
2.2 There are more than 100 Hammerheads in the Hammermill crusher. It takes a lot of time and manpower to replace one set of hammerheads. The cost of overhaul and maintenance is high. And the replacement of the bottom sieve plate is also extremely troublesome.
3.2 the hammerhead is in the state of hanging, and the wear occurs on the upper, front, back and side. Compared with the Board Hammer, wear is more serious. The utilization rate is only about 35%. And the rotor body itself may also be subject to wear. The bottom screen plate is seriously affected by wear and tear. The screen grating should be completely replaced and more complex.
5.1 The plate hammer of the impact machine is fixed on the rotor. It can make full use of the energy of the whole rotor when crushing and is favorable for crushing large materials. Because it has an impact plate and bigger crushing cavity. The crushing not only depends on the impact of Hammer but also on the repeated impact between material and counter plate or between material and material.
6.1 There is no grate bar at the bottom of the impact machines. The particle size of the product is determined by the clearance between the impact plate and the hammerhead. It can avoid blocking when the moisture content of the material is too high.
To sum up, if the materials require high, humidity high and output is large, then must choose impact crushers. If the output requires low (less than 30 tons per hour), and no requirement on the finished grain shape can be used hammer crusher.

Processing Materials: silica, iron ore, granite, gangue, river pebbles, calcite, limestone, bluestone, coal, gypsum, glass, cement, bricks, tiles, and some mental ores.
Hammer crusher is also called hammer mill crusher or industrial hammer mill, which can be used in the dry or wet crushing processes. It can crush materials into the required size in one time to save lots of energy and investment costs.
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.
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.
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.
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.
