Jaw Crushers are heavy machines used to impart an impact on a rock particle placed between a fixed and a moving jaw. It uses compressive force and consists of a set of vertical jaws, one stationary (Fixed jaw) and other moving (Swing jaw), one eccentric shaft for cam mechanism, cylindrical roller bearings, pulley, balancing mass, motor engine and framing.

The mechanism of movement of rocks down the crusher chamber determines the capacity of jaw crushers. The movement can be visualised as a succession of wedges (jaw angles) that reduce the size of particles progressively by compression until the smaller particles pass through the crusher in a continuous procession.

A Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening). For instance, a 24 x 36 jaw crusher has a opening of 24" by 36", a 56 x 56 jaw crusher has a opening of 56" square.
