The longest and most robust crusher is the jaw crusher. It reduces large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw – a movable jaw and a static jaw. They simulate the movement of the animal’s jaws to complete the material crushing operation. The jaw crusher is widely used in mining, building materials, chemical industry, metallurgy

The jaw crusher is not so efficient a machine as the gyratory crusher described in the next paragraph, the chief reason for this being that its crushing action is confined to the forward stroke of the jaw only, whereas the gyratory crusher does useful work during the whole of its revolution. In addition, the jaw crusher cannot be choke-fed, as can the other machine, with the result that it is

Jaw crushers are generally installed on top of the concrete foundations. Take into consideration of the weight of jaw crusher, the tough working conditions and the high inertia forces generated by the machine during operation, which may cause the slight vibration of foundation and machine system; therefore, the foundation of the jaw crusher should be separated from the foundation of the workshop.

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.
