Primary Jaw Crusher

Introduction:

The main structure comprises a frame, an eccentric shaft, a big belt wheel, a flywheel, a movable jaw, a side guard plate, elbow plate, elbow plate back seat, gap adjusting screw rod, a reset spring, a fixed jaw, a movable jaw plate and other components, wherein the elbow plate also plays the role of insurance.

Primary jaw crusher is used for the primary crushing operations in stone production line, sand production line and other production lines. The stone are sent to the feed port by the belt conveyer, after the extrusion in the crushing chamber composed of movable jaw plate, fixed jaw plate and the side boards, the finished material is the discharged from the lower discharge part of the equipment.

Working Principle:

This series of jaw crusher adopts the crushing style 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 mass production.

Primary jaw crusher has the advantages of big crushing ratio, uniform product size, simple structure, reliable operation, easy maintenance and low operating costs.
