Jaw crusher composition and working principle

This machine is mainly composed of frame, moving jaw, eccentric shaft, jaw plate, bracket and other parts, the frame is the whole cast steel structure, the frame front wall is equipped with wedge bolt fixed jaw plate, The side panels of the racks are fitted with side guards to prevent wear on the side walls of the rack.

Jaw crusher composition and working principle

The movable jaw is a wear-resistant cast steel with an active jaw on the front and an eccentric shaft and a roller bearing on the upper part of which are suspended from the frame and the lower part is supported on the bracket and in rolling contact with the bracket, End with a flywheel and pulley.
The other end of the bracket is supported on the adjustment seat and is in rolling contact with the bearing. In addition to supporting the moving jaw, the brackets play a supporting role in the external jaw crushing material into the crushing chamber. Insurance role, that is, their rapid fracture, while protecting other components from damage.
Adjust the size of the material when the adjustment seat installed in the rack on both sides of the chute, and wedge tight with the tune, when the discharge port needs to be adjusted, the nut with a wrench to the right hand, adjust the wedge immediately increase, With the seat forward move, discharge from the big mouth becomes smaller, on the contrary from small to big.
working principle
When the motor drives the belt and pulley, the moving jaw is moved up and down by the eccentric shaft. When the moving jaw rises, the angle between the bracket and the movable jaw becomes larger, thus pushing the moving jaw to approach the fixed jaw, and the material is crushed Or broken, broken to achieve the purpose of broken; when the moving jaw down, the bracket and moving jaw angle becomes smaller, moving jaw in the rod, under the action of the spring, leaving the fixed jaw plate, this time has broken material from the crushing chamber Mouth discharge, with the continuous rotation of the motor crusher jaw for periodic movement of crushing materials, broken into the ideal particles discharged from the discharge port.
