Working principle and main components of impact crusher:
The impact crusher is mainly composed of a rotor body, a front impact plate, a rear impact plate and a body. During operation, the rotor body is driven at a high speed by a belt drive, and the falling material is impacted by the impact of the plate hammer and thrown back to the impact plate. In the crushing cavity, the material and the material collide with each other for selective crushing. The front and back impact plates break the material after repeated impact routes for a certain time and length, and the particle size is smaller than the gap between the impact plate and the plate hammer, and finally discharged from the material port.
The main components of the impact crusher are springs, railings, front impact racks, rear impact racks, impact liners, square steel, impact liner bolts, clamshells, spindles, hammers, rotor frames, liners, locking blocks, Compression block and so on.
Working principle of industrial hammer crusher:
The hammer crusher crushes materials mainly by the impact of the hammer of the crusher. In the lower part of the rotor, a sieve plate and materials enter the crusher and are immediately crushed by the impact of the high-speed rotating hammer. The size of the crushed material that is smaller than the size of the sieve hole is discharged through the sieve plate, while the larger particle size material, which rebounds to the granular material of the liner, will also be crushed by the additional impact of the hammer head. During the entire process of material crushing, the material They also smashed against each other. The crushed material obtains kinetic energy from the hammer head, and impacts on the lining plate on the inner wall of the casing at a high speed and is crushed a second time. Finally, it is discharged out of the machine through a sieve plate (sieve bar).
Industrial Hammer Crusher
Impact crusher manufacturers share with you: the difference between impact crusher and hammer crusher:
1. Different crushing cavity
The impact crushing chamber is large, and the inlet is low and large. The crushing of the material not only depends on the impact of the hammer, but also the repeated impact between the material and the impact plate or the material and the material. To better crush large pieces of material. The hammer-broken crushing cavity is small and the structure has good sealing performance, which solves the problems of dust pollution and ash leakage in the crushing space.
2. The direction of action of the hammer / hammer head is different
The counterattack hammer is used to meet the material from the bottom to the top, and it will throw the material on the counterattack board above. The hammer crusher is crushed in the direction of the falling material.
The counter-rotating rotor rotates clockwise, and the hammer strikes the material from bottom to top
The hammer breaks the rotor and rotates counterclockwise, and the hammer head strikes in the direction of the falling material.
3. Different wearing parts wear differently:
The hammer and the hammer head are the main wearing parts of counterattack and hammer respectively. The wear of the hammer of the impact crusher mainly occurs on the side facing the material, and the metal utilization rate of the hammer can reach 45% -48%.
4. Different ways of adjusting the discharge:
There is no purlin sieve in the lower part of the impact crusher. The adjustment of product particle size can be controlled by adjusting the rotor speed or rotor diameter, adjusting the size of the opening of the distributor, and adjusting the gap of the grinding chamber.
5. Rotor links are different:
The hammer and rotor of the impact crusher are rigidly linked, that is, the hammer is fixedly mounted on the rotor. When crushing, the inertia of the entire rotor can be used to impact the material. kinetic energy.
