The principle of Impact crusher crushing

Impact crusher crushing principle

The impact force is used to break the material. When the material enters the crushing cavity, it will be broken into smaller particles by the impact of the high-speed rotation of the rotor and the impact of the impact plate. At the same time, the material will be repeatedly impacted and broken in the crushing cavity until it reaches the required crushing particle size. Finally, the crushed materials will be discharged from the discharge port to complete the entire crushing process.

Specifically, the working process of the impact crusher can be divided into the following steps:

Feeding: Materials enter the crusher through the feeding port and fall into the high-speed rotating rotor.
Impact crushing: The material collides with the plate hammer on the rotor, resulting in crushing effect. At the same time, the rotor also throws the material to the impact plate, so that the material is impacted and broken again.
Repeated crushing: The material is hit and crushed multiple times in the crushing cavity until it reaches the required crushing particle size. During this process, materials will also collide with each other, further increasing the crushing effect.
Discharge: The crushed materials are discharged through the discharge port to complete the entire crushing process.
It should be noted that the crushing effect of the impact crusher is related to factors such as the rotation speed of the rotor, the shape and number of plate hammers, and the angle of the impact plate. Therefore, when using an impact crusher, it is necessary to select appropriate operating parameters and structural forms based on specific material properties and production requirements.
