Four roller crusher is a crushing machine researched and manufactured by our company for coarse crushing. The roll crusher is widely used for crushing high hard and medium hard materials in such industrial departments such as metallurgy, building material and refractory. It has the features of low noise, little powder dust, reliable performance and convenient maintenance.
Four roll crusher is mainly used for secondary and fine crushing to materials below middle hardness, such as coking coal, clinker mineral, limestone, metallic and nonmetallic ore. Roll crusher is available for ore dressing, chemical, cement, refractories, abrasive, building materials industries, finely crushing all kinds of ore and rock below the high, medium hardness,which can make the minimum grain size below 100 mesh,especially in the building materials industry to produce melon meters stone and green bean products etc, and have the more excellent effect than general stave machinery , in recent years, also widely used in crushing steel grit industries.
Four roll crusher is fixed with four high-strength resistant grinding rollers. Four rollers relative rotation generates high extrusion pressure and shear force for crushing the material. Firstly the material enters into the space between the topside two rollers. Here, it is extruded, rolled and sheared (coarse crushing) by the the topside two rotation rollers. Secondly the material extruded and milled (fine crushing) by the bottom two rolls which are relatively rotating. under the extrusion, cut and mill of the bottom two rolls, the material becomes the required size , sent by the transport equipment.
1. Average discharging size without blocking up.
2. Automatically screening the materials after crushing.
3. High efficiency and low energy consumption.
4. Good flexibility and operational reliability.
5. Full-sealed design and no dust pollution.
6. Small vibration and low noise.
7. Removable shell which is convenient for daily maintenance and inspection of the machine.
