Working Principle of stone jaw crusher:
Jaw crusher consists of frame, eccentric shaft, belt wheel, flywheel, movable jaw, side guard plate, toggle plate, toggle backseat, gap adjusting screw, returning spring, fixed jaw plate and movable jaw plate. Toggle plate is also used to guarantee the security.
Jaw crusher uses electric motor as the motive power. Eccentric shaft is driven by triangle belt and genea wheel, which makes movable jaw make reciprocating motion according to the desired trajectory. Then, materials in crushing chamber (consists of fixed jaw plate, movable jaw plate and edge plate) are crushed and the finished materials are discharged from discharging hole.
Features of jaw crusher:
1. Crushing chamber depth and no dead zone, increased capacity and output feed
2. Big crushing ratio, uniform particle size.
3. Gasket nesting population adjustment device, reliable and convenient, big adjustment range, increase the flexibility of the device.
4. Lubrication system safe and reliable, easy to replace parts, maintenance workload is small.
5. Simple structure, reliable operation, low operating costs.
6. Energy-saving equipment: Single machine energy saving 15% ~ 30%, the system energy saving more than double
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.
