PEW Jaw Crusher Working Princple

The PEW jaw crusher is developed on the base of jaw crusher, so the working principle is similar to the PE series. But the hydraulic system is added. This working manner of jaw crusher is hyperbolic extrusion. And its working principle is as follows. Through the motor's wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jaw plates move by a regulated track. The angle between the toggle plate and jaw plates will become large as the up of the jaw stock. This will push the moveable jaw plate towards the fixed jaw plate, which can realize the multi-crushing of the materials. The angle between the toggle plate and jawstock will become small as the down of the jawstock. The moveable jaw plate will leave the jaw plate at the pressure of the tension rod and spring , meanwhile ,the final products will be discharged from the discharge opening. Along with the continuous rotating , the crusher will complete the periodic crushing and discharging movement ,which can realize the batch process.
