Frequently Asked Questions

SBM impact crusher machine use the impact energy to break rock or other materials. When the impact crusher works, the motor drives the rotor where the plate hammers fixed rotate with high speed .The raw materials are crushed in the crushing cavity. And the high-speed rotating rotor casts the crushed materials along tangential direction to impact plate at the other end of the crushing cavity. The materials are crushed again, and then, they return to the plate hammer to undergo the process above repeatedly. The materials are bumping with each other when being sent between the plate hammer and the impact plate. The materials become cracked, loose and then comminuted by knocking by the plate hammer, impact with impact plate and bump between materials. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged.
