The History Of Jaw Crusher
A jaw crusher is one of different types of crushers often used in crushing rocks, mining s well as in a plant where ore is being processed. In order to break and crush particles, the jaw crusher makes use of what is known to be a compressive force. A jaw crusher is powered either by a diesel or electric motor meaning that operations can be

Jaw Crusher Working Principle
A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar: the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the Dodge motion, being the resultant of the circular motion of the

1 Introduction Jaw and cone crushers are commonly used in the mining and aggregates industry. Today, it is possible to predict the performance of a cone crusher, provided the geometry, crusher settings and the characteristics of the material fed into the crusher are known ( Evertsson, 2000 ). The geometry of the crusher will change because of wear.
