working principle of jaw crusher

The structure of jaw crusher contains the frame, eccentric shaft, big belt pulley, flywheel, movable jaw, side guard plate, toggle plate, rear seat of toggle plate, modulation gap screw, returning spring, fixed jaw plate and movable jaw plate, etc, among which the toggle plate is used for safety. The working mode of this series crushers is pressing deviously. The motor drives the belt pulley and the belt pulley drives the eccentric shaft to rotate, and make the moving jar approach and leave the fixed jaw periodically, to crush, rub and grind the materials repeatedly, thus to make the material slower and slower and gradually fall down and finally discharge from the discharge opening.
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.



This crusher machine is a kind of crushing equipment of a long history, featuring simple and firm structure, reliable operation, convenient maintenance and repair and low operation cost, so it is still widely used in metallurgy, chemical, building material, power, communication and other industries, for the primary, secondary and tertiary crushing of ores and rocks with the compressing strength of 147～245Mpa, to crush materials of different sizes to uniform small grains. It can be used with the ore dressing equipment or used independently.
This crushing machine can be used to produce the aggregate for subgrade, railway ballast and construction sand and stone.It divided into the coarse jaw crusher and the fine jaw crusher,PE series and PEX series.

benefits of jaw crusher

One of our main products, Jaw Crusher is designed by our engineers with large reduction ratio, even granularity, simple structure, reliable operation, convenient maintenance, low cost, Jaw Crusher is widely used in mining, metallurgy, construction, highway, railroad, and chemistry industries.

application of jaw crusher:

Our jaw crusher are ideal for primary and secondary crushing. With the increase of production, our jaw crusher can greatly reduce the operating costs. And it is of reliability and flexibility. The large feed opening and force-feeding action from the inward and downward eccentric movement of the swing jaw mean that our jaw crusher can increase the capacity.
