The impact crusher
is a relatively common medium and fine crushing equipment. The impact crusher working principle mainly uses the high-speed rotating plate hammer on the rotor to produce high-speed impact on the material sent into the crushing cavity and crush it, and the crushed The material is thrown to the impact board at the other end of the crushing chamber at a high speed along the tangent direction, and is broken again, and then rebounds from the impact board to the hammer, and the above process is repeated. During the round trip, the materials still collide with each other. Because the material is hit by the blower, impacted by the counterattack plate, and the materials collide with each other, the materials continue to produce cracks, loose and crush. When the particle size of the material is smaller than the gap between the impact plate and the blow bar, it is discharged. Impact crushers are mainly used for metallurgy, chemical industry, building materials, hydropower and other materials that often require relocation operations, especially for mobile stone operations such as highways, railways, and hydropower projects.

impact crusher working principle
:First, the impact crusher motor drives the rotor to rotate through the triangular belt. At this time, the blow bar on the rotor is radiating under the action of centrifugal force. When the material enters the range of the blower's rotation from the inlet, it will be impacted by the high-speed rotating blower, and thrown to the impact board along the tangential direction of the blower's rotation. Then, it returns from the counterattack plate to the hammer rotation space and enters the impact zone of the second counterattack plate. The material is subjected to the repeated impact of the plate hammer, the counterattack plate and the impact in the crushing cavity, which continuously produces cracks along the joint surface of its own, and the internal organization is damaged, loosened and broken. The particles smaller than the crushing requirement will be discharged out of the machine along the gap between the hammer and the impact plate, which becomes the crushed product.
The impact crusher uses the plate hammer on the high-speed rotating rotor to produce high-speed impact on the materials sent into the crushing chamber to crush
The crushed material is thrown to the impact board at the other end of the crushing chamber at a high speed along the tangential direction, and is crushed again
Then rebound from the counterattack board to the hammer, and continue to repeat the above process
During the round trip, the materials still collide with each other.
Due to the impact of the blower, the impact of the impact board and the collision between the materials, the materials continue to produce cracks, loose and crushed
When the impact crusher crushes the material, the material is suspended and is impacted by the plate hammer. If the particle size of the material is small, the impact force will pass through the particles, and the material will be thrown in the tangential direction. If the particle size of the material is large, the material will rotate when it is thrown, and the throwing direction is at an angle of υ with the tangent direction. In order to make the material block penetrate into the hammer action circle and reduce the rotation, the lower part of the feeding slide bends downward.
