Working Principle of Primary Crushers. The working principle of primary crushers varies depending on the type of crusher, but generally, they work by reducing the size of the material through compression or impact. In jaw crushers, the material is fed into the crushing chamber and is crushed between a fixed jaw and a movable jaw.

Gyratory crushers may seem like complex machines, but their principle of operation is surprisingly straightforward. At its core, a gyratory crusher consists of a mantle that rotates within a concave bowl-shaped housing. As the mantle gyrates, it creates a crushing action by compressing the rock against the stationary concave walls. ...
