Product Features

1, long service life, not easy to damage. 2. Compact structure, light weight and small size. 3, the structure is simple, the space is small, and the operation and maintenance are convenient. 4. Simple and reasonable structure, low operating cost, stable operation, high efficiency and energy saving, high crushing efficiency. 5. The inside is equipped with a dustproof plate, which has good sealing performance and avoids the splashing of fine materials after crushing. 6. The discharge particle size can be adjusted. After the roll gap is adjusted according to the requirements of the crushing particle size, the crushing particle size can be controlled, and all of the same granularity is discharged from the bottom of the crushing chamber.

Working Principle

1. The roller crusher is mainly composed of a roller, a roller support bearing, a pressing and adjusting device, and a driving device.
2. Adjustment of discharge particle size: wedge or washer adjustment device is installed between the two rollers, and the top of the wedge device is equipped with an adjustment bolt. When the adjustment bolt pulls up the wedge, the wedge will lift the movable roller off. The fixed wheel, that is, the gap between the two rollers becomes larger, and the discharge granularity becomes larger. When the wedge is downward, the two rollers of the movable roller become smaller under the action of the pressing spring, and the discharge granularity becomes smaller. The gasket device adjusts the size of the discharge by increasing or decreasing the number or thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge granularity becomes smaller. .
3. The driving mechanism is driven by a motor, and is driven by a V-belt to the groove wheel to drag the roller and rotate in the opposite direction. When the material is crushed, the material passes through the roller from the feed port and is crushed by rolling, and the broken product is discharged from the bottom of the chassis.
4. For safety, the transmission part should be installed with a safety cover according to the actual situation.
