What is roller crusher?

The roller crusher is kind of crushing machine using two opposite rotating rollers to crush material. It is mainly composed of rollers assembly, roller support bearing, pressing and regulating device and driving device. It is suitable for fine crushing process with feed size less than 80mm and finished product size from 50μm-20mm. For example, crushing pebbles and construction waste to make artificial sand, fine crushing iron ore, quartz stone in mining, crushing raw materials in ceramic industry, and in the coal industry, it can be broken directly after removing iron and impurities. It is suitable to crush coarse and brittle bulk materials, with large feeding particle size and adjustable discharging particle size.

Why choose roller crusher?

After entering the crusher, the material is crushed by rolling and grinding shear force of the roller. Double roller crusher has feataures of simple compact structure, light body, stable and reliable performance, large crushing ratio.

The roller crusher is driven by two motors full of power. And the most important highlight of roller crusher is the discharge can be adjusted. Users can adjust the crusher according to their own finished material needs.

We produce smooth roller crusher and teeth roller crusher. It needs to choose suitable model according to material features, moisture, crushing ratio, output size, capacity etc.Baichy Machinery could advise suitable crushers for you.

Product features

Uniform Particle Size Output

Two rollers create continuous compression crushing, producing evenly sized materials with fewer fine particles and better product control.
Low Over Crushing Rate

The squeezing crushing method reduces excessive material breakdown, helping maintain desired product size and improve material utilization.
Adjustable Discharge Size

Roll gap can be adjusted according to production requirements, allowing flexible control of final product specifications.
Durable Rollers and Low Maintenance

Its simple mechanical design requires minimal maintenance. The rollers are wear-resistant chromium molybdenum copper alloy with long service.

Working principle

The materials to be crushed fall from the feeding mouth to the space between the two rolls.After being squeezed and crushed, the final products will naturally fall. When there are too hard materials or materials that cannot be crushed, the rolls of the roller crusher will automatically withdraw under the effect of hydraulic cylinder or spring to increase the gap between the rolls, and the too hard materials or the materials that cannot be crushed will fall down.Thus protecting the machine from being damaged. There is a certain gap between the two rolls that rotate at the opposite direction, and the maximum discharging granularity of the final products can be controlled by changing this gap. Double roller crusher's the materials by relying on the two round rollers rotating at the opposite direction, and four-roll crusher crushes the materials by relying on the two pairs of round rollers rotating at the opposite direction.
