Four roll crusher is a kind of metallurgical mine equipment, which could medium crush and fine crush. It also could get the required particle size through the clearance adjustment of the upper and lower rollers. The Φ1200 * 1000 900 * 700 and Φ900×700 four roll crusher have the advantages of compact structure, small occupied area, large crushing ratio (18: 1) and higher yield.
Four roll crusher suitable for compression strength less than 200Mpa, humidity less than 30% of the hard and medium hard material crushing operations. Such as coke, coal, ceramic raw materials, quartz, feldspar, limestone, slag, gypsum, clay, salt, chemicals and other solid materials. This machine has the low maintenance costs, large broken ratio, reliable performance, little dust, low noise characteristics
Four roll crusher is grinding with four high-strength wear-resistant alloy roller. The high extrusion force and shear force from relative the rotation could break the material. After the material into the top two roller V-type crushing chamber, squeeze force the two rollers by the relative rotation. And then go into the middle two rollers, use of the middle roller squeezing forces to secondary extrusion and gripping (fine break), then go into the two lower rolls. Use the lower two roller for the third squeezing, shearing and grinding (superfine, Applicable to the four-roll crusher type) broken into the required particle size and then transfer out by the conveyor equipment.
