Crushing and breaking of rock, ore and minerals is one of the oldest industries undertaken by man. The earliest crushing known was by hand on 'native' ores (gold, silver, and copper) or on ores containing lapis lazuli, garnet, diamond, jade, etc. The earliest US patent for a crushing machine was issued in 1830.

In jaw crushers, the crushing force is generated by the movement of the movable jaw plate towards the fixed jaw plate. This force is a result of the mechanical pressure created by the eccentric shaft and transmitted through the toggle plate. The interesting thing is how these forces are applied to the material.

Crushers have more efficient transfer of applied power to the breakage of rock than grinding mills. Typically a crushing flowsheet for a mineral processing plant will have from one-to-three stages of crushing.
