Impact Crusher is a crushing machine that uses impact energy to crush materials. When the machine is working, motor drives the rotor rotates at a high speed. When the material enters the impact area of the blow bars, it hits and breaks with the blow bars on the rotor, and then it is thrown to the counterattack device which is called breaker plates and broken again, and then rebounds from the breaker plates. Return to the rotor action area to re-crush.

This process is repeated. The material enters the first, second, and third impact chambers from large to small, and is repeatedly crushed until it is crushed to the required size and discharged from the discharge port.

 

Blow bars are thick slabs of metal, typically some mixture of chrome, that are forged for the purpose of effectively breaking apart material like asphalt, concrete, limestone, etc.
Blow bar is a critical part during the crushing process with horizontal shaft impactor. Materials of the blow bars are usually selected according to the function of the impact crusher.
