How does vertical mill work?
Vertical mill’ development is to solve low output, energy consumption and higher technical problems of industrial mill. LM series vertical grinding mill is an ideal equipment that integrates crushing, drying, grinding and grading conveyor all together. Vertical Mill can be used to crush the lump , particle and powder raw materials to the required powder materials .And now LM series Vertical Mill has found its extensive application in the field of Cement, electric power, metallurgy, chemical industry, non-metallic mineral etc. Here we talk about the working process and working principle of vertical mills.
The motor drives the grinding table through decelerator. The materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. Due to the centrifugal force, materials move to the edge of the grinding table. The materials are pulverized by the roller when by pass of the groove on the grinding table. The crushed materials are brought up by vane high-speed airstream, the larger particles fall down to the grinding table for regrinding. When the materials in the airstream pass the separator on the top of the mill , the coarse powder fall down the grinding table for regrinding under the function of rotation rotor. The fine powder comes out with the airstream, and is gathered by the dust catcher. The materials content with moisture will be dried when they meet the hot airstream. Through adjusting the temperature of the hot airstream, it can meet different material’s requirement, and also through adjusting seperator, it can reach proper fineness of materials.
