Overview Of Vertical Mill
Vertical Roller Mill is a new kind of large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years’ research of mills, Vertical Roller Mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand. It adopts reliable structure and reasonable process flow, integrated with drying ,milling, classifier , elevator. Especially ,it can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level.
LM series vertical grinding mill is the newest grinding machine, which integrates the advanced international technology and years of mill-producing experience . It is an ideal equipment that integrates crushing, drying, grinding and grading conveyor all together.
The application of Vertical Mill
LM series vertical grinding machine can be widely used in cement making, power,metallurgy, chemical and nonmetalliferous ore industries. It is used to grind lumpy, granular and powdery materials to the required size.
Specialized for the high production of superfine pyrophyllite powder making in glass fiber industry Specialized for the high production of gangue powder making in coal industry Specialized for the high production of various of chemical raw material powder making in the chemical industry. It is a necessary equipment for the high production of mineral powder in the non-mental mine industry and large scale powder making in many other industries.

Working principle of Vertical Mill
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.
