1.Motor drives belt and pulley,dynamic jaw movement up and down through eccentric shaft .

2.When the movable jaw plate rises , the angle between bracket and fixed jaw becomes smaller, so as to promote dynamic jaw plate close to the fixed  jaw, at the same time the material is crushed or splited, achieve the  purpose of broken;

3.When the movable jaw plate downward, the angle between bracket and the movable jaw becomes bigger , the broken material flow out from crushing cavity mouth.

Performance of fine jaw crusher:

1.This fine jaw crusher has centralized lubrication system,  more easy to maintain
The unique design of centralized lubrication systems, lubricated components more efficient, small maintenance workload.
2.The fine jaw crusher has a simple structure, high efficiency
Under the basic principle of compound pendulum, streamlining of redundant parts, overall structure of the device is simple and efficient, strong crushing capacity, easy operation and maintenance, low operating costs.
3.This fine jaw crusher has a wide discharge adjustment range
More than one machine, gasket-type discharge adjustment device, large material adjustment range, increase the flexibility of the device when used to meet a variety of customer processing requirements.
4.The machine works with low noise, less dust,more environmental 
The device according to the national environmental standards, low noise, can be equipped with the device dust, construction environment in full compliance with environmental requirements.
