【What’s the double roller crusher】
The Doule Roller Crusher, also known as roll crusher, or toothed roll crusher, is suitable for fine crushing medium hardness rock with compressive strength ≤160MPa, such as ore, rock, coke, coal, clinker, ceramic raw materials, slag, refractory materials, and chemical materials.
According to the number of rolls, the roll crushers can be divided into single-roll crushers, double-roll crushers, or four-roll crushers. Double roll crusher is the most used type. We produce industrial roller crushers and the laboratory uses small roll crushers.
【Advantages】
- Replacement wear-resistant lining, long service life, convenient maintenance.
- Compact structure, lightweight, small size, for the same production capacity requirements of the crushing system, equipped with a roller crusher can significantly save investment.
- The width of the discharge opening can be adjusted to determine the crushed material size.
- High reduction ratio, low vibration, dust removal, and less noise.
- High efficiency, low consumption, uniform granule, good granule shape.

Product Structure
【Main Parts】Bearing box, roll shell, bearing housing, adjusting rod, motor, carrier, fixed roller, movable roller and safety spring, etc.
【Working Principle of Double Roller Crusher】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.
【Operation】The main wearing part of the roller crusher is the crushing roller. Precautions as follows:
Iron removal before crushing; prevent sticky mud clogging; pre-pick out the large ore rock; good lubrication condition.
