Jaw Crushers

Mechanical pressure is applied using the crusher''s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds of materials of any hardness, as well as their low-cost operation and easy maintenance.

b. Crushing | Cement Production

A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom opening.

On oscillations of a vibratory jaw crusher with asymmetric …

The value of Δ φ = 180° corresponds to the synchronous antiphase rotation of the exciter''s debalances, which causes the antiphase oscillations of its jaws required for the crusher''s normal operation. When Δ φ = 0°, the debalances rotate in phase, exciting the common-mode oscillations of the crusher''s jaws.
