Vertical roller mill is a set of grinding equipment, grinding, drying and crushing, separating and transporting in one, is widely used in all kinds of solid materials, cement, building materials, electric power, metallurgy, chemical industry, non-metallic mineral industries such as grinding and ultra fine grinding.
Vertical grinding mill is composed of a set of grinding device (i.e. grinding roller and grinding) to complete, the material is milled into powder between grinding roller and grinding. The movement of the rotating disc milling device and the corresponding drive roller mill grinding roller pressure transmission, in addition to weight, mainly by a set of hydraulic device of disc material pressure. The existence of a large number of coarse powder milled powder material, selected by the powder selecting machine, powder of powder is the result of flow separation in the flow process, most of the coarse powder to receive automatic disc grinding, again, the rest of the powder selecting machine selected for finished products, by collecting and conveying system into the finished product storage.
The residence time of the material in the disc is mainly decided by three factors: one is the effect of centrifugal force of the grinding disc speed; two is the internal friction material and the grinding disc friction and material itself; three is to determine the motion mode and structure of roller mill and the coordination between the. And the third factor is the key to determine the vertical roller mill factory design, different grinding roller and grinding form determines the residence time of the material in grinding speed and grinding plate. Users in the selection of vertical mill must choose appropriate according to the characteristics of vertical roller mill grinding material.
