Working Principle

The working principle of jaw crusher is very simple. The whole crushing process rely on the relative motion of the two jaw plates. One of the jaw plates is fixed and stay still, the other moves against it by a cam or pitman mechanism.
During this movement, the materials between the two plates would be crushed progressively into small particles: while the plates move against each other, the materials would be crushed, and while plates move apart from each other, the broken materials which are smaller enough would drop through the discharging opening. The movement of the jaw can be quite small, since complete crushing is not performed in one stroke. Due to the simple structure, jaw crusher is easy to maintain and repair. These features promote its popularity to a great extant.
