Usage of double roller crusher
The Double roller crusher is suitable for the secondary and fine crushing of solid materials (the compressive strength less than 300MPa) with various hardness, medium hardness or soft ones, such as iron ore, cement clinker, coal, coke, slag, coal gangue, pebbles, limestone, silicon ore, quartz stone, concrete, chemical raw materials and so on. It is widely used in the industries of mining, cement, thermoelectric, metallurgy, building materials, chemical and so on. The roller crusher is welcomed by the users for its' excellent features, such as the low maintenance investment, low power consumption, high crushing ratio, high efficiency, reasonable structure, no dust pollution, small vibration and so on.
Working principle
Double-roll crusher is fixed with two high-strength wear-resistant alloy rollers. Their relative rotation generates high extrusion pressure which crushes the material. The material enters into the space between the two rolls, suffered both extrusion and shear force. In the crowd rolling, cutting and grinding, it is crushed into the required size and then discharged from the base of the machine.
