Roller press is designed according to the principle of material bed grinding, its main features are: high pressure, full speed, full material, material bed crushed. The roller press is composed of two squeezing rollers that rotate in synchronism with each other. One is a fixed roller and the other is a moving roller.
The material is fed from above the two rollers, and the squeeze roller is continuously carried into the roller. After being subjected to a high pressure of 100-150 MPa, the compact cake is discharged from the machine. The discharged cake, in addition to containing a certain percentage of fine finished products. In the interior of non-finished products, a large number of cracks are generated, which improves the grindability of the materials, and in the further crushing process, the grinding energy consumption can be greatly reduced.
