Detailed Description

Vertical Grinding Mills are a newest grinding machine with decade of research of mills, Vertical Grinding Machine is designed and manufactured based on our advanced design idea, in combination with the European technology and the market demand. LM Vertical Grinding Mill VM series Vertical Grinding Mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of research of mills, vertical grinding mill is designed and manufactured based on our advanced design idea, in combination with the european technology and the market demand. VM Vertical Roller Mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meet the requirement of clients of the high production of powder, and its main technical and economic indicator reaches the international level. Features: Low running costsIt adopts the technology that vertical roller grind material directly on the disc, with low energy consumption; for the roller is not contact with the disc directly in the work, and the roller and liner are made by quality materials, it is of less wear and long life. Simple and reliable operationIts automatic control system can reach remote control, which is easy to operate; there is the device to prevent roller sleeve contact with disc liner directly, and avoid the destructive impact and severe vibration; we can turn the rotating arm by repairing fuel tank, replace the roller and liner are more convenient, which can reduce the downtime. Energy conservation and environmental protectionIt features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills. Working Principle: 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 materials requirement, and also through adjusting separator , it can reach proper fineness of materials.
