7. Nesting population has big adjustment range, to meet the requirements of different users .

8 . Low noise, little dust.

Advantages of jaw crusher

1. Effectively solves the problem of high operation rate and little maintenance time caused by low output of limestone crusher.

2. Can complete the crushing work of large-sized limestone.

3. The blending of the two materials is even and the mixing quantity of the desulfurized limestone is greatly increased.

4. The electricity needed is reduced.

5. The granularity of the wastes is small.

6. Effectively improves the labor strength and the working environment of the workers.


operation of jaw crusher


Structure and wroking principle of jaw crusher

The structure of Jaw Crusher includes main frame, main axle, roller bearings, eccentric shaft, jaw plates, side plates, toggle mechanism, fly wheels and springs.

The strip and strip pulley are driven by a motor, and the moving jaw moves up and down via eccentric shaft. The angle between fixed jaw and moving jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It will become bigger when the moving jaw runs up. The moving jaw board leaves the fixed jaw board under the action of pole and spring, and then the end products come out from the crushing cavity. And also, Jaw crusher is always used as the Primary jaw crusher.

Operations of jaw crusher

1. Start feeding after checking the machine.

2. Evenly put the material into the machine, and avoid putting material from the side or feeding too much to avoid over-feeding, sudden load change or blocking.

3.Stop feeding before stopping machine. Stop motor after all material discharged.

4.Stop the motor if there is any stagnancy due to the blocking up of material inside the machine.

5.The other side can be used if one side of fixed jaw plate and movable jaw plate is worn.

6. Check all fixed parts before starting to use and tighten the part if loose.
