1. The relative sliding difference between the grinding wheel and the grinding roller of the vertical mill is small, the white fungus allows the grinding stone to rotate at a faster speed, and the working pressure of the grinding roller is higher, so the output is higher than that of other types of grinding rollers under the same specifications. High power saving.

2. It can dry, grind and powder the materials at the same time, with simple process and low noise.

3. Is the English wind sweep type and part of the material external circulation system, the latter can greatly reduce the ventilation power consumption of the system.

4. The internal ventilation annulus can be flexibly adjusted according to the distribution of the material on the grinding table surface to reduce the ventilation resistance and reduce the power consumption.

5. For the four roller vertical roller mill, the grinding roller can press the roller separately or the four rollers at the same time to adapt to the change of the material bed. If the grinding roller is separately pressurized, different working pressures can be used to make the work. The pair of grinding rolls with less pressure which has the dual function of preparing the material bed and the grinding powder, which plays an important role in maintaining the stability of the material bed when the roller grinding material is more difficult to grind under a higher working pressure. During operation, the working pressure can be set according to the running condition of the grinding roller. The hydraulic pressurization system has a suitable stiffness design and a wide range of adjustments to accommodate different fragile materials.

6. The grinding roller can be automatically lifted to achieve no-load starting to reduce the starting torque of the motor.

7. Roller grinding can be turned out of the casing by turning the roller cylinder for maintenance.

8. Built high-efficiency cage type powder sorting machine, the fineness of adjustment is sensitive, the load is strong, and the powder selection efficiency can reach more than 90%.
