Jaw Crusher is widely used aggregate crusher to crush all kinds of materials with a compressive strength lower than **0MPa in mining,metallurgy,public road,railway,hydropower and many other industries.The basic structure of a jaw crusher generally includes seven parts such as driving medium,rack,the jaw plate and side rack ,flywheel,lubrication device,adjusting device and the reset spring.

The main structure of the Jaw Crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.

This Jaw Crusher's crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising ,the included angle between the wrist plate and movable jaw becomes bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing;

When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.
