The type and working principle of jaw crusher

　　Jaw crusher appeared in 1858, it is an ancient crushing equipment, but because of the simple structure, reliable work, easily manufacturing, convenient maintenance, so it still has wide application in metallurgical mine construction materials, chemical industry and railway departments. It is mostly used for hard and medium hard ores crushed and broken. jaw crusher is usually classified according to the moving jaw plate (dynamic) of jaw function features.
　　There are two main types which are the most widely used in the industry.
1, mobile jaw does simple swinging double knee mechanism, that is so called jane pendulum.
2,mobile jaw does complex single bracket swinging agencies, that is so called compound pendulum. Hydraulic technology has been applied on crushing equipment, a hydraulic jaw crusher appeared.

1,Blake crusher-fixed in the lower point
2,Dodge crusher-fixed in the upper point
3,Universal crusher-fixed in the midpoint

　　Jaw Crusher Working Principle: Jaw stone crusher: Through the triangle belt, the flywheel is driven by the motor. Then the flywheel drives the eccentric shaft to make the movable jaw plate do reciprocating motion. Materials will be crushed when the movable jaw plate move towards to the fixed jaw plate. End products will be discharged through the discharging opening when the movable jaw plate move backwards.
　　Nowadays, the PEW Jaw Crusher in European style undoubtedly becomes the most welcome products in the world.
