Rock crushers are machine build to break large rocks into much smaller rocks, gravel, or sometimes rock dust. They are an important tool for most commercial mining operations. Rock crushers usually hold the rocks to be crushed in between two solid surfaces and apply a force that forces the molecule of the materials to separate or change alignment.

Typical hard-rock crushers like jaw, gyratory and cones break rock by nipping the ore between a fixed/stationary and a moveable wear-resistant surface/liner. How much reduction each crushing stage is capable of infliction of rocks (reduction ratio) is driven by the angles between the 2 surfaces on each side and holding the rocks-to-be-crushed ...
