Jaw Crusher

Jaw crusher is crushing stone equipment with long history. It is widely used in metallurgy, mechanical industry, building material, power, transportation until now, because it is simple in structure, b, reliable, easy for maintenance and repair, and with low cost. It can crush rocks with strength of 147-245Mpa. As everybody knows, the main disadvantage of jaw crusher is that lifetime of jaw plates is short. In order to solve this problem, our company has developed special material for it. Also fluid coupling is used in large model jaw crusher to improve start process, and avoid overload.

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 after crushing will be discharged from the outlet.
Jaw Crusher Operating principle:
This jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.
