Illustration of How Jaw Crusher Crushes

A jaw crusher reduces large size rocks or ore by placing the rock into compression, a fixed jaw, mounted in a “V” alignment is the stationary breaking surface, while the moveable jaw plate exerts force on the rock by forcing it against the fixed jaw plate. The space at bottom of the “V”, aligned jaw plate， is the crusher product size gap, or the size of the crushed product from the jaw crusher.
Due to the advantage of simple structure, reliable performance, convenient maintenance and safe use, our jaw crushers of various sizes are widely used in the crushing operation in metallurgy, mining, building materials, chemical industries and cement enterprises.

Working Principle of Jaw Crusher:

The motor transmits power through belt, drives the moving jaw do periodic motion to the fixed jaw surround the eccentric shaft. The angle between toggle plate and moving jaw increases when moving jaw moves up. So the moving jaw closes to the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves away from fixed jaw by the pulling of rod and spring, the products such as stone after crushing will be discharged from the outlet.
