Jaw crusher stone crusher
PE/PEX Series Jaw Crushers is of single toggle type with features of simple structure, easy maintenance, stable function, low operation cost, great crushing ratio. It is used widely in mine, metallurgy, construction, road, railway, hydro-electric, and chemistry. It is suitable for the primary or secondary crush of large rock with compressive resistance no more than 320MPa. PE type is used for primary crushing, and PEX type is used for secondary and fine crushing.
Features and technology advantages
Working principle
Powered by electrical motor, movable jaw is set in reciprocating movement at predetermined track through the transmission system of driving wheel, Vee-belt, and eccentric roll-driving shaft. The material is crushed in the cavity composed by fixed jaw plate, movable plate, and side protecting plate, and discharged the end product from the bottom discharge opening.This series jaw crusher adopts curve-movement compression way to crush the material. electric motor drives belt and belt wheel to set the movable plate in moving up and down through eccentric shaft. When the movable jaw rises, the angle formed by toggle and movable plate will be wider, and the jaw plate will be pushed approaching the fixed plate. In this way, the materials are crushed through compressing, grinding, and abrading. When the movable plate descends, the angle formed by toggle and movable plate will become narrower. Pulled by rod and spring, the movable plate will move apart from toggle, so the crushed materials can be discharged from the bottom of the crushing cavity. Consecutive movement of motor drives the movable plate in circular crushing and discharge to realize large-quantity production.
