Detailed Description
Application The Roller crusher can be classified into single roller, double roller crusher and four roller crusher according to the roller quantity. And it is mainly used for middle crushing and fine crushing of all kinds of ores and rocks in mid-hardness(such as coke, lump, coal, slag, mineral slag, cement clinker, etc.)in mine, chemical industry, cement, building materials and other industrial sections. 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. Features 1. 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. 2. Adjustable product size, no dust& noise pollution.3. It is effectively used in minerals crushing where the ores are not too abrasive and it is also used in smaller scaleproduction mining of more abrasive metal ores, such as gold. 4.
