Summary：Jaw crusher machine adjustment device is used to adjust crusher discharging port size. It is mainly composed with adjustment wedge, auxiliary hydraulic cylinder and the locking lever.
Jaw Crusher Adjustment Device
Jaw crusher machine adjustment device is used to adjust crusher discharging port size. It is mainly composed with adjustment wedge, auxiliary hydraulic cylinder and the locking lever. With the machine operation, the toothed plate is worn and the discharging port size will be more and larger. The final product size will be more and coarser. To guarantee the final products size requirements, it must use the adjustment device and adjust the discharging port size regular. 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 device: gasket adjustment, wedge adjustment. Gasket adjustment needs human adjust the gasket and put them into the space between back thrust plate pedestal and rack back wall to adjust the discharging port 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 it also is the 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 disadvantage is that it does not have enough reaction sensitive. The material of bracket is HT150.
Jaw Crusher Flywheel and Sheave
Motion will bring the sheave move through belt wheel 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 balance the sheave weight and then it will store the energy.
