working principle of Jc jaw crusher

The JC series of Jc jaw crushers in European style are mainly consist of frame, the rotation part of the eccentric bearing, the working part of the crushing cavity, the safety unit and the adjustment devices of the discharging opening.
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 Jc 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 Jc jaw crusher and the fine Jc jaw crusher,PE series and PEX series.
