Crushing is the reduction of large material into smaller sizes. It is often one of the first steps in any aggregate or mineral processing plant and is accomplished with various types of crushing equipment. These machines employ various forces to reduce the material to the required size.

The crushing process can be accomplished in one or more stages - primary, secondary, tertiary and quaternary - and include a variety of crusher types.

Selecting the right crusher for an application begins with a consideration of all the components of the crushing process, including the factors that affect the crushing process (feed size, product size, capacity and reduction ratio) and the following factors that affect the crusher type:

-Type of material or its abrasiveness

-Hardness of the material or its friability

-Density or toughness of the material

-Fragmentation or particle shape

-Condition (ambient weather, clay in the material, etc.)
