Impact crushers. An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor. Secondary breakage then occurs as the material is accelerated into the stationary aprons or breaker plates.

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher.
