Working Principle of LM Series Vertical Mill2,Low investment cost, low operation cost, high drying ability,reliable operation, stable quality, convenient maintenance, pro-enviroment when using the Vertical Mill.
The motor of the Vertical Mill 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 Vertical 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 of the Vertical Mill 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 Vertical 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, the Vertical Mill can meet different material’s requirement, and also through adjusting seperator, the Vertical Mill can reach proper fineness of materials.
