What is a Jaw Crusher

The jaw crusher is a classic stone crushing equipment invented in 1858,it has two jaw plates moving close and apart, crushing big lumps of stones into smaller size. For any production line that contains stone crushing process, the jaw crusher is a maust-to-have machine to carry out the first-stage crushing task.

1. Motor drives the belt and pulley, making the moving jaw plate moves up and down through the eccentric shaft. 

2. When the moving jaw plate rises, the moving jaw plate and the stationary jaw plate come close, and the material between the two jaw plates is crushed.

3. When the moving jaw plate goes down,  the moving jaw plate leaves the stationary jaw plate, and the crushed material is discharged from the lower opening.

4. The moving jaw plate performs periodic crushing and discharging to realize big capacity crushing process.
