4.  Small footprint, compact layout, light weight of system equipment, and low investment in civil construction.

Solution

For the treatment of high-moisture materials, the drying capacity of the vertical mill is required to be high. The drying capacity of the vertical mill should be regarded as an important direction for equipment selection. The three capabilities of , drying and powder selection are scientifically and reasonably matched. On the premise of ensuring that the materials meet the drying requirements, the output of grinding and powder selection can be brought into full play, so as to achieve reliable, efficient and energy-saving equipment selection;

For the treatment of low-moisture materials, since the vertical mill is essentially a material bed grinding, when the moisture of the incoming material is too low, it is difficult for the material to form a stable material layer on the grinding disc after entering the vertical mill, which will cause the vertical mill. Abnormal vibration, unable to run stably. In order to ensure the stable operation of the vertical mill, it is necessary to solve the problem of how to stabilize the material layer. Generally, the measures that can be taken include active means (such as controlling and adjusting the thickness of the material layer, grinding pressure, height of the retaining ring, slag discharge, etc.) and passive means (such as adding a water spray device, etc.), on the premise of giving priority to ensuring the grinding capacity At the same time, it is reasonable to take into account the powder selection ability of the vertical mill.
