Roll crusher is also called double roll crusher, double teeth roll crusher etc. The surface of roller crusher are made of high manganese steel, which can stand up to heat treatment. Double roller crusher is suitable for rough and intermediate crushing of brittle materials in such industries as cement, chemical industry, electric power, mine, building materials and metallurgy. The grain size of the input material is large, the particle size of the output product can be controlled, and it is possible to effectively destroy the material whose compressive strength is less than 160 MPa.
Roller crusher has widely application in mining, building materials, chemical industry, metallurgy, etc. It is mainly used for secondary and fine crushing of materials with middle hardness or middle minus hardness, such as rocks, coal, slag, clinker mineral, shale and so on. Depending on the requirements, the rolls are smooth or toothed.
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.

Advantages
1. The rollers is wear-resisting chromium molybdenum copper alloy with long service. 2. The gap between the rollers is adjustable, so that the output size and capacity will be changed accordingly. 3. This crusher is equipped with motorless scraper. When the raw material has high moisture content, it can avoid to affect the output size and avoid sticking the roller or blocking the machinehe. 4. According to requirement, it could be in flat roller or toothed roller.
