    An impact crusher (also called a hammer crusher) is quite versatile. It can be used as a primary, secondary, or tertiary crusher. Impact plates and beaters or hammers are used to break down the material. The material is fed through the upper part of the crusher then hit by hammers. Next, the pieces are thrown toward the plates. This further breaks the material. The pieces bounce back
