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.

Although the hammer crusher and impact crusher are somewhat similar in appearance, they are quite different. How to choose between the two? This article will compare them from the scope of processing materials, structure, price, output, etc.
Impact crusher: It has a relatively large crushing cavity, so the material is not only impacted by the hammer, but also repeated impacts between the material and the impact plate, and between the material themselves.
That is, the rotor operates clockwise inside the impact crusher, while in the interior of the hammer crusher, the rotor operates counterclockwise. The hammer head strikes along the direction in which the material falls.
Hammer crusher: Due to the overhanging state of the hammer head of hammer crushers, the wear occurs on the upper, front, back and side. Compared with the plate hammer, the hammer head is more seriously worn with the metal utilization rate about 35%, and the rotary body itself may also be worn.
Impact crusher: The plate hammer and the rotor are rigidly linked inside the impact crusher, that is, the plate hammer is fixedly installed on the rotor. It can make full use of the inertia of the entire rotor with great speed and kinetic energy to impact the material during crushing.
Impact crusher: There is no screen grate at the bottom of the impact crusher, so the adjustment of the product particle size is mainly controlled by adjusting the rotor speed or rotor diameter, the opening size of the distributor and the gap of the grinding chamber.
Therefore, in situations where cubic particles are needed, for example, the anti-skid pavement of high-grade highway, the impact crusher can be used as the crushing equipment to produce concrete aggregates.
The crushing granularity of the heavy hammer crusher is larger, and the reference price is about $5,000-180,000. The heavy hammer crusher can form a single production line to simplify the crushing process.
Impact crusher: Relatively speaking, the material is not prone to be clogging in the impact crusher. Firstly, it can be equipped with a heating device to prevent the material from blocked due to adhesion.
Secondly, there is no grate at the bottom of the impact crusher. The product size is determined by the gap between the impact plate and the plate hammer. Therefore, it can be used to handle materials with excessive water content to avoid blocking the grate.
It only takes one shift to replace a set of plate hammers and the replacement of the grinding rod in the bottom grinding chamber takes only a few minutes, which greatly reduces the time and cost of overhaul and maintenance.
Hammer crusher: There are more than 100 hammer heads in the hammer crusher. It takes a lot of time and manpower to replace one set of hammerheads, and the cost of overhaul and maintenance is high. The replacement of the bottom screen is also extremely troublesome.

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.
