double roller crusher:

PG double roller crusher from United Tech Machinery is also called 2 Roller crusher. We have 2 kinds of twin roller crusher, one with the surface as teeth, another with the surface of the roller as smooth. utmach brand roller crusher are made of high manganese steel, which can stand up to heat treatment. Double roller crusher is suitable for such industries as cement, chemical industry, electric power, mine, building materials and metallurgy. Mainly used for secondary and fine crushing materials with soft or middle hardness like coal, coke, limestone, coal, coke, clinker, granite, basalt, cement, brick, tile, building material etc. 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 strength is less than 160 Mpa.

Working principle:
The materials 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.

Double Roller Crusher advantages:
1. Compact structure, reliable performance
2. Low noise and high efficiency

3. Easy to install and only need simple foundation
4. It can adjust the pressure and size easily, and can be made to meet the customer's request
5. Low attrition rate and easy to maintenance
