PC roller crusher

The PG double-roll crusher is an environmentally friendly, low-dust, low-noise crushing device primarily composed of rollers, roller support bearings, a clamping and adjustment device, and a drive unit. A wedge-shaped or spacer adjustment device is installed between the two rollers, allowing for flexible adjustment of the discharge. The crushed material is cubical and has a fine particle size. It is widely used in metallurgy, chemical industry, electric power, transportation, and other fields, and can perform medium and fine crushing of both hard and soft ores.

Performance Features

01

Strong Load Capacity

Large feed size and strong compressive resistance enable crushing of materials with a compressive strength of ≤160 MPa.

02

Easy Discharge Size Adjustment

A wedge or gasket adjustment device is installed between the two rollers, making discharge size easy to control and ensuring safe operation.

03

Low Investment Cost

With its compact structure, light weight, and small size, the double-roll crusher can save investment for grinding equipment with the same production capacity.

04

Low Noise and Low Dust

An internal dust shield provides excellent sealing, preventing the splashing of fine materials after crushing. The low noise level effectively improves the working environment.

Working principle

During operation, crushed material falls through the feed opening between the two rollers, where it is squeezed and crushed, and the finished product is discharged through the lower outlet. A wedge-shaped or shim adjustment device is installed between the two rollers of the double-roll crusher. The top of the wedge-shaped device has an adjustment bolt. When the adjustment bolt block is pulled upward, the wedge pushes the movable roller away from the fixed roller, increasing the gap between the two rollers. When the wedge block is pulled downward, the gap between the movable roller and the fixed roller is reduced by the action of the compression spring, resulting in a smaller discharge size. The shim device adjusts the discharge size by increasing or decreasing the number or thickness of shims. Adding shims increases the gap between the two rollers, while removing them reduces the gap.
