The Double Roller Crusher, also known as a roll crusher or toothed roll crusher, is suitable for fine crushing of medium-hardness rocks with a compressive strength of ≤300MPa. It is widely used for processing materials such as ores, rocks, coke, coal, clinker, ceramic raw materials, slag, refractory materials, and chemicals.

According to the number of rolls, the roll crushers can be divided into single-roller crushers, double-roller crushers, or four-roller crushers. Double roller crusher is the most used type.
We offer both industrial roller crushers and small roll crushers for laboratory use.

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.

Advantages

Replaceable wear-resistant lining for long service life and easy maintenance.
Compact structure, lightweight, and small footprint, making it a cost-effective choice for high-capacity crushing systems.
Adjustable discharge opening for precise control of product size.
High reduction ratio, stable operation, low vibration, minimal dust, and reduced noise.
High efficiency, low energy consumption, uniform particle size, and excellent grain shape.

FAQ

Q: What materials are suitable for double roller crushers?
A: Ideal for medium-low hardness materials (coal, limestone, coke) with low over-crushing rate. Not for ultra-hard ores.

Q: How to adjust output size of double roller crushers?
A: Change roll gap via hydraulic/mechanical system: wider gap for coarser output, narrower for finer.

Q: How to fix uneven roller wear?
A: ①Rotate rolls regularly ②Check feed distribution ③Replace wear-resistant alloy rollers if severely worn.
