Product Description

PG double roller crusher is an environmentally friendly crushing equipment with low dust and low noise. It is mainly composed of rollers, roller support bearings, compression and adjustment devices, and driving devices. A wedge-shaped or gasket adjustment device is installed between the two rollers, which can flexibly adjust the discharge. The crushed materials are cube-shaped and have fine particle size. They are widely used in metallurgy, chemical industry, electric power, transportation and other fields. Medium and fine crushing of soft ores.

Product Performance

Working Principle

During operation, the crushed materials fall between the two rollers through the feeding port for squeezing and crushing, and the finished products are discharged from the lower outlet. A wedge or gasket adjustment device is installed between the two rollers of the double-roller crusher. There is an adjustment bolt at the top of the wedge device. When the adjustment bolt block is pulled upward, the wedge pushes the movable roller away from the fixed wheel. The gap becomes larger. When the wedge moves downward, the gap between the two movable rollers becomes smaller under the action of the compression spring, and the discharge granularity becomes smaller. The gasket device adjusts the discharge particle size by increasing or decreasing the quantity or thickness. When the gasket is added, the gap between the two rollers becomes larger, and when the gasket is reduced, the gap becomes smaller.
