Machine construction

It is mainly composed of frame, eccentric shaft assembly, large pulley and flywheel, movable jaw, fixed jaw plate and movable jaw plate, elbow plate, adjusting device, motor and other main components

Working Principle

The crushing mode of jaw crusher is curved extrusion crushing. During operation, the motor bends the belt and pulley to make the moving jaw move up and down through the eccentric shaft. When the moving jaw rises, the included angle between the elbow plate and the moving jaw becomes larger, so as to push the moving jaw plate close to the quota plate. The materials are crushed multiple times through extrusion, rubbing and grinding between the two jaw plates; When the movable jaw descends, the included angle between the elbow plate and the movable jaw becomes smaller. The movable jaw plate leaves the fixed jaw plate under the action of pull rod and spring. The crushed materials are freely discharged through the discharge port at the lower part of the jaw cavity under the action of gravity. With the continuous rotation of the motor, the movable jaw performs periodic crushing and discharging to realize mass production. The speed is generally 180-300 revolutions per minute.
