What Is Roller Crusher?

A double roller crusher is a crushing machine that uses two counter-rotating rollers to compress and crush materials between the roller surfaces. Compared with traditional crushing equipment, the roller crusher provides gentle crushing performance with a lower over-crushing rate. The distance between the two rollers can be adjusted, allowing operators to control the discharge size efficiently. With a compact structure, adjustable discharge size and stable operation, it is widely used in sand making plants, coal crushing systems and mineral processing plants. Baichy provides customized smooth roller crusher and toothed roller crusher solutions according to material, capacity and final product sizes.

Why Choose Roller Crusher?

Double roller crusher is suitable for various fine crushing requirements requiring controlled crushing and uniform particle size.

1. Sand Making Plants. The roller crusher can be used for fine crushing of limestone, river stone, quartz and other materials to produce qualified sand-making feed materials. In middle-east, Baichy's double roller crusher is applied to make high-quality manufactured sand using limestone as raw material.

2.Coal Crushing. The low-impact crushing method helps reduce excessive powder generation and is suitable for coal preparation and power plant applications. Baichy supplied a double-roller crusher in Indonesia for coal crushing , handling soft, medium-hard coal with uniform output size. The unit runs stably with low powder generation and helps the customer reduce maintenance cost in daily coal processing.

3.Mining and Mineral Processing.The roller crusher can be used for secondary and fine crushing of various mineral materials with suitable hardness.Baichy exported doule roller crusher for secondary fine crushing processng in stone crusher plant

Lower Over-Crushing Rate

The compression crushing principle produces uniform particles, reduces unnecessary powder generation and improves final product quality..
Customized Solution

According to material, capacity and final product requirements,Baichy provides smooth roller crusher, tooth roller crusher, hydraulic type roller crusher etc.

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.
