Development of vertical mills in the cement production industry Compared with the ball mill in the cement industry, the vertical mill has the following advantages: simple process, strong adaptability of raw materials, convenient maintenance, and more environmental protection and energy saving. Internationally, the cement engineering industry has a high acceptance of vertical mills. In raw meal grinding and coal grinding, vertical grinding is basically used; in cement clinker grinding, vertical grinding is mostly used. Vertical Milling Process Features Compared with the ball mill grinding system: (1) Grinding, drying and classification are completed at the same time. There is no need to set a separate powder separator, so the system process is simple. Small footprint, saving infrastructure investment; (2) Use hot exhaust gas to dry the material during the grinding process, saving energy; (3) The power consumption per unit grinding is reduced by 35-40%, and the unit metal wear is only 1/10 ~ 1/20 of the ball grinding; (4) Strong adaptability, can grind brittle materials with high moisture and various hardness; (5) Adaptation to large-scale needs: throughput: 3000 ~ 4000tph

Compared with the high-pressure roller grinding system: (1) Grinding, drying and classification are completed at the same time. There is no need to set a separate powder separator, so the system process is simple. Small footprint, saving infrastructure investment; (2) Both belong to the principle of material layer grinding, and the unit power consumption is equivalent; (3) The vertical mill can grind brittle materials with high moisture and various hardness; (4) Adapt to large-scale needs: throughput: 3000 ~ 4000tph; (5) The individual parts are small and convenient for maintenance and transportation....
