Jaw Crusher Components & Parts

Jaw Crusher Adjustment Device

Jaw crusher machine adjustment device is used to adjust crusher discharging port size. It is mainly composed of adjustment wedge, an auxiliary hydraulic cylinder and the locking lever. During operation, the toothed plate wears, and the discharge opening becomes larger and larger. The final product size will be more and coarser. To guarantee the final product size requirements, it must use the adjustment device and adjust the discharging port size regularly. At the same, when the production line produces unqualified size products, it also needs to adjust the discharging port size.

In the market, there are two kinds of adjustment devices: gasket adjustment and wedge adjustment. Gasket adjustment requires workers to adjust the gaskets and place them into the space between the rear thrust plate pedestal and the rack back wall to adjust the discharge opening size. The wedge adjustment will adjust the discharging port size through the hydraulic cylinder. You can add hydraulic into the cylinder, the wedge will move and it will change the discharging port size. This method is very convenient.

Jaw Crusher Insurance Device

The insurance device is composed with bracket, bracket, spring, spring rod. The bracket will play insurance function under the abnormal condition. The bracket is also called as toggle plate. It is not only the part can transport motion to moving jaw, but also an insurance device. When hard materials enter into the jaw crusher machine, the bracket will firstly be cut down and it will avoid other parts damage. This method’s disadvantage is that it does not have sufficient sensitivity. The material of bracket is HT150.

Jaw Crusher Flywheel and Sheave

Motion drives the sheave to move via the pulley and belt. Sheave and eccentric shaft is connected through the keyless locking devices. The sheave will bring the eccentric shaft rotating and then it will bring moving jaw move. It will realize the material crushing.

Flywheel is installed on the other side of eccentric shaft. Its main function is to balance the sheave weight and store energy.
