Hammer crusher operating principle

Driven by the motor, the rotor of hammer crusher which consists of main shaft, disk, pin shaft and hammers rotates at high speed in the crushing cavity. Raw materials enter the cavity through the feed opening. Materials in the cavity are blown, impacted and ground by the hammer. Below the rotor is the sieve plate, which screens the materials.

Materials in the hammer crusher that reach the required size can be discharged from the sieve plate, while the oversize materials will be left and crushed again until reach the standard size. The final product size of the hammer crusher can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement
