The FTM CJ jaw crusher is the new type first stage crush equipment designed by FTM engineers, it has higher crush ratio and low maintenance cost than the traditional jaw crushers, the people in mining field will find CJ jaw crusher looks like the art in a group crusher machines because it has more reasonable structure, you will not worry about the shake of the machine, yes, low noise and the parts will not loose in the working process.




FTM CJ jaw crusher working principle

A jaw crusher uses compressive force for breaking of particle. This mechanical pressure is achieved by the two jaws of the jaw crusher of which one is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw, called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small, since complete crushing is not performed in one stroke. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric motion that causes the closing of the gap.
