The Roller Crusher bears the features of stable operation, easy maintenance, low cost, and adjustable output size. The Roller Crusher can be used in the processing of fragile materials in cement, metallurgy, chemical, power generation, and coal industries.
Working Principle of double roller crusher:
Through the feed opening, the raw materials fall to between the two rollers, after crushed, the final products drop naturally. When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and make the hard or unbreakable so as to avoid the machine damage. The clearance between the two rollers can be adjusted to change the sizes of final products.

Application of double roller crusher:

It is widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, and so on.
