Roller Crusher Overview

The Doule Roller Crusher, also known as roll crusher, toothed roll crusher, is suitable for fine crushing the medium hardness rock with compressive strength ≤160MPa, such as ore, rock, coke, coal, clinker, ceramic raw materials, slag, refractory materials, and chemical materials.

Roller Crusher Types
According to the number of rolls, the roll crushers can be divided into single-roll crushers, double-roll crushers, and four-roll crushers. A double-roll crusher is the most used type. We produce industrial roller crushers and the laboratory uses a small roll crusher.

Double Roller Crusher Working Principle
The roller of the roller crusher is supported by the spring pressure. Under normal working conditions, the spring force is sufficient to overcome the crushing force of the crushed material. By changing the number of spacers between the frame and the movable bearing, the width of the discharge port between the two rolls can be adjusted to adjust the grain size.
When there is a material that cannot be broken into the crushing chamber, the spring is compressed, and the movable roller is retracted to increase the discharge opening. After the material is discharged, the movable roller is reset under the spring pressure.
