. To provide more suitable coal mill, we usually require our customers to tell us their materials exact information including production site environment and requirement, raw materials size and hardness, desired capacity and final size.

LM vertical coal mill has been widely applied for coal crushing. There are 6 models for vertical coal mill that are LM130M, LM150M, LM170M, LM190M, LM220M and LM240M. As an advanced coal mill, the vertical coal mill adopts top-ranking technology home& abroad and is designed based on many years of manufacturing experience of grinding mills.

Apart from coal mill, vertical coal mill is also widely used in such industries as cement making, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.

How does Vertical Coal Mill work ?

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 pass 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 fixed on the top of the coal grinding 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 separator, it can reach proper fineness of materials.
