【Product advantages】
1. High grinding efficiency, vertical mill adopts grinding roller and material bed to grind and grind materials, low energy consumption, power consumption of grinding system is 40~50% lower than that of ball milling system, and as the humidity of raw materials increases, electricity is saved The effect is more pronounced.
2. Strong drying capacity. The vertical mill uses gas to convey materials. When grinding materials with high moisture content, the inlet air temperature can be controlled to make the product reach the moisture content. The vertical mill can dry materials with a moisture content of up to 12~15%. Materials, even the drying ball mill, can only dry materials with a moisture content of 3~4%.
3. The particle size of the material to be milled is large, and the secondary crushing can be omitted for large and medium-sized vertical mills.
4. The chemical composition of the product is stable and the particle gradation is uniform.
5. The process flow is simple, the building area is small, and the space is small. There is a separator in the vertical mill, and there is no need for a powder separator and a hoist. Simple and compact layout.
6. Low noise, less dust, and clean operating environment
7. The metal loss is small, and the life of the lining plate and the grinding roller is long.
