Jaw Crusher Main  Application
1, This group of crushers mostly are useful for metallurgical, mining, chemical, cement, construction, fireproof materials and ceramics along with other industrial sector in secondary and tertiary crushing, dealing with various hard minerals and rocks.
2, The most appropriate anti-pressure strength for this number of crushers will be the materials(minerals, rocks, slag) no more than 280Mpa. The feeding sized materials should not be a larger than the specification within the technical parameter.

Working principle of jaw crusher :
The main structure of the  stone 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 become 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.
