The roller bearing is lubricated by forced thin oil and equipped with a hydraulic roller turning device. During maintenance, the grinding roller can be turned out of the machine by the hydraulic device. The maintenance space is large, the maintenance is convenient, and the operating cost is low.

7. High-efficiency ring protection
The entire production line adopts a negative pressure closed circulation system, and is collected by a high-efficiency pulse dust collector, without dust spillage, which meets the latest national environmental requirements.

8. Integrated comprehensive solution
A professional technical service team provides users with design, supply, installation and general contract services, and integrated comprehensive solutions, saving worry and effort.

【An Introduction】
HVM vertical mill can process materials with high water content of 20%~30% (such as carbide slag, lignite, etc.) to materials with water content less than 1% (cement clinker, etc.), and has strong adaptability to the moisture content of materials.

【Solution】
For the treatment of high-moisture materials, the drying capacity of the vertical mill is required to be high, and 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.). At the same time, it is reasonable to take into account the powder selection ability of the vertical mill.
