1. This series of roller crusher is mainly composed of roller, roller bearing, pressing and adjusting device and driving device.
2. Adjustment of discharge granularity: There are wedge-shaped or gasket adjusting devices between the two rollers. The top of the wedge device is equipped with adjusting bolts. When the adjusting bolt lifts the wedge upwards, the wedge moves the moving roller off. The fixed wheel, that is, the gap between the two rollers becomes larger and the size of the discharged material becomes larger. When the wedge is down, the two rollers of the movable roller become smaller under the action of the compression spring, and the discharge granularity becomes smaller. The gasket device adjusts the size of the material by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller and the particle size of the discharge becomes smaller. .
3. The drive mechanism is composed of two motors, which drive the drag roller through the V-belt drive to the sheave, and rotate according to the relative direction. When the material is crushed, the material passes through the roller from the feed port and is broken by rolling. The broken product is discharged from under the bottom frame.
4, for safety, the transmission part should be based on the actual situation to install the safety cover.
Double roll crusher working principle
Adjustment of discharging particle size: There are wedge-shaped or gasket adjusting devices between the two rollers. The top of the wedge device is equipped with adjusting bolts. When the adjusting bolt lifts the wedge upward, the wedge moves the moving roller away from the fixed wheel. That is, the gap between the two rollers becomes larger, and the size of the discharged material becomes larger. When the wedge is down, the two rollers of the movable roller become smaller under the action of the compression spring, and the discharge granularity becomes smaller. The gasket device adjusts the size of the material by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller and the particle size of the discharge becomes smaller. .

Uses: The roller crusher is reliable, simple in maintenance, low in running cost and adjustable in discharge particle size. According to the number of rollers can be divided into two-roll crusher and four-roll crusher, can be widely used in cement, metallurgy, chemical, electric power, coal and other industries for brittle and tough materials processing.
