1. The series of jaw crushers are mainly composed of rollers, roller support bearings, pressing and adjusting devices and driving devices.

2. Adjustment of discharging granularity: wedge or gasket adjusting device is installed between two rollers, and adjustment bolt is installed at the top of wedge adjusting device. When the adjusting bolt pulls the wedge upward, the wedge lifts the movable roller from the fixed wheel, that is, the clearance between the two rollers becomes larger, and the grain size of the discharged material becomes larger. When the wedge is downward, the clearance between the two wheels of the movable roller reduces and the grain size of the discharged material decreases under the action of the compression spring. Gasket device adjusts the size of discharged material by increasing or decreasing the number or thickness of gaskets. When the gasket is added, the clearance between the two rollers becomes larger, and when the gasket is reduced, the clearance between the two rollers becomes smaller, and the grain size of the discharged material becomes smaller.

3. The driving mechanism is driven by two motors through a triangular belt to pull the roller on the groove wheel and rotate in the relative direction. When crushing the material, the material passes through the roller from the inlet and outlet, and is crushed by rolling. The crushed product is discharged from the bottom of the chassis.

4. In order to be safe, the transmission part should install the safety cover by itself according to the actual situation.
