« Usage and Application
The kind of roller crusher is also known as the double roller crusher, roll crusher, roller machine, it can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, etc., is widely used for secondary and fine crushing in the industries like mining, building materials, cement, chemical industry, etc.
« Working Principle
The materials are put into the space between the two 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 materials between their rotating surface into the ever smaller gap area, as the two rollers inward turning, the input materials are crushed, pressed, ground and at last come out from the base of the machine.
