Rollers crusher can be classified into double roller crusher and four roller crusher according to the roller quantity. It bears the features of stable operation, easy maintenance, low cost, output size adjustable. The products can be used in the processing of fragile materials in cement, metallurgy, chemical, power generation, coal industries.
Working Principle:
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 damaging the machine. The clearance between the two rollers can be adjusted to change the sizes of final products.
Features:
Double roller crusher can adjust the clearance between rollers and drive through triangle belt or multidirectional shaft coupling, and the four roller crusher will do it only through triangle belt.
