The impact crusher is a kind of crushing machine which uses impact energy to crush materials. When the machine works, driven by the motor, the rotor rotates at high speed. When the material enters the action zone of the plate hammer, it impacts and crushes with the plate hammer on the rotor, and then is thrown to the impact device to crush again.

In an HSI crusher, a horizontal rotor shaft spins rapidly to deliver powerful blows along the chamber's length using bars, hammers, or plates to impact material. In a VSI, a vertically oriented rotor spins and propels rock against enclosed chamber walls or curtains at speeds up to 75 mph for crushing.
