 Product Introduction

The double-roll crusher mainly crushes materials by squeezing and shearing force. It is widely used in mining, metallurgy, building materials, chemical industry and other industries to crush ores, coal, limestone, coke and other materials of various hardness. It has the characteristics of large crushing ratio, high production capacity and uniform crushing fineness. During use, it is necessary to make reasonable selection and adjustment according to the characteristics of the material and the crushing requirements to ensure the crushing effect and the normal operation of the equipment.

Product Advantages：

1. Small size, large crushing ratio, large crushing capacity, low noise, simple structure and easy maintenance.

2. The crushed materials have uniform particle size, low over-crushing rate, convenient maintenance, sensitive overload protection, safe and reliable, etc.

3. For the coal industry, it can be directly crushed, and the crushed materials have uniform particle size and low crushing rate.

4. Simplify the process and reduce investment and production costs

How it works：

Adjustment of the particle size of the material: A wedge or shim adjustment device is installed between the two rollers. An adjustment bolt is installed on the top of the wedge device. When the adjustment bolt pulls the wedge upward, the wedge pushes the movable roller away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the particle size of the material becomes larger. When the wedge is downward, the gap between the two wheels of the movable roller becomes smaller under the action of the compression spring, and the particle size of the material becomes smaller. The shim device adjusts the particle size of the material by increasing or decreasing the number or thickness of the shims. When the shims are increased, the gap between the two rollers becomes larger, and when the shims are reduced, the gap between the two rollers becomes smaller, and the particle size of the material becomes smaller. The driving mechanism is composed of two motors, which are driven by a V-belt to the groove wheel to drag the rollers and rotate in relative directions. When crushing materials, the materials pass through the rollers from the feed inlet, are crushed by rolling, and the crushed finished products are discharged from the bottom of the chassis.
