In the working process of the machine, the rotor rotates at a high speed driven by the motor. When materials enter the crushing chamber, they will be impacted and crushed by the blow bar on the rapidly turning rotor, and then thrown to the impact plate for a secondary breaking, finally rebounded back to the rotor area and be crushed again.
