10. Backfill unwanted rock and fine material (mine reclamation) During reclamation, the mined pit is backfilled with a mix of unwanted rock (from step 2) and reject materials (from steps 5, 6, and 9). As the mine wall is excavated, the area behind it is continuously being filled in.
Crushers are used to reduce particle size enough so that the material can be processed into finer particles like powders in a grinder. So, a typical processing line at a mine might consist of a crusher followed by a SAG mill or a ball mill. In this context, grinding mills like ball mills are considered grinders rather than crushers.

A typical impact crusher or other type of rock crusher uses a great deal of force to reduce the size of rocks. They operate on mechanical force for breaking apart the large rocks as opposed to chemical or laser methods of breaking rocks. In many cases, primary crushers are a part of a large materials handling system.

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54" across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
