Jaw crusher application
Jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by V-belt and groove wheel to make the movable jaw move by a regulated track. Therefore, the materials in the chamber that consists of fixed jaw, movable jaw and side plate can be crushed and discharged from the discharge opening.

Jaw crusher working principle

1. The frame

The frame of jaw crusher is heavily loaded during work: thus it is of high strength and rigidity. The frame is welded(cast-steel for the small jaw crusher). The fixed jaw is installed at the front of the frame by a high-strength bolt. The up and down side-plates are installed at the left and right side of the frame.

2. The main parts

The movable jaw is made of high quality cast steel. The precise machining and strict testing ensure that its high reliability and safety.

The fixed jaw, like the movable jaw, is made of high-manganese steel. It is designed symmetrically; so if one end is frayed, the other end can still be used.

The eccentric shaft is made of forging steel, which is of high strength and rigidity.

The bearing adopts four sets of the self-aligning roller bearing; it has a great loading capacity and auto self- aligning.

The fly wheel and groove wheel are made of cast iron. Its weight and the structure can ensure the balance of the crusher.
