What is a Jaw Crusher and Selecting the Right One

The Working Principles Of A Jaw Crusher. All jaw crushers operate on the same straightforward principle; two hard-faced heavy plates or jaws crush large particles between them. One powered jaw reciprocates in an elliptical motion opposite a stationary jaw mounted in the frame. During an operating cycle, the gap between the two jaws opens; a ...

How to Maximize Crusher Efficiency

The materials are squeezed in between a moving piece of steel and stationary steel. To maximize the efficiency of this type of crusher, avoid the trickle feeding method because this can lead to poor productivity and cause a negative impact on the bearing alignment. Instead, aim between 75% to 95% power range.

Assessing the energy efficiency of a jaw crusher

Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
