double roller crusher
Double roller crusher usage and technical specifications:
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.Double roller crusher is mainly used for secondary and fine crushing materials with soft or middle hardness like coal, coke,limestone etc.
Working principle:
The particles are drawn into the gap between the rollers by their rotating motion and a friction angle formed between the rollers and the particle, called the nip angle. The two rollers force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rollers.
Features:
- The rollers is wear-resisting chromium molybdenum copper alloy with long service.
- The gap between the rollers is adjustable, so that the output size and capacity will be changed accordingly.
- 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.
- According to requirement, it could be in flat roller or toothed roller.
