Vertical roller mill is a kind of ideal large grinding equipment, widely used in cement, electric power, metallurgy, chemical industry, non gold metal mines and other industries. Vertical roller mill sets the crushing, drying, grinding, grading conveying in one, the production efficiency is high, the powdery material can be massive, granular and powder grinding materials required. The first vertical mill is developed in Germany in twentieth Century 20.

Some people say, the grinding principle of it is similar to our ancestors milling grain mill, which adopts the bed grinding principle of grinding material, overcomes many defects of ball mill grinding mechanism, has the advantages of high grinding efficiency, low power consumption (20%~30% ratio of ball mill power-saving), drying capacity, allowing large feeding size, grinding process is simple, small occupation area, low construction cost, low noise, little abrasion, long service life, easy to operate.

Vertical milling machine is suitable for medium and small mines, chemical industry, building materials, metallurgy, refractory materials, pharmaceutical, cement and other industries. For the block, granular and powdery raw material grinding mill like material requirements. Widely used in metallurgy, building materials, chemical industry, mining and other fields, grinding processing of mining products, suitable for processing a Mohs hardness of seven below the level of humidity below 6%, in a variety of non flammable and explosive minerals, such as gypsum, talc, calcite, limestone, marble, feldspar ore, barite, dolomite, granite, kaolin, Peng Runtu, Chinese medical stone, bauxite, iron oxide red, iron ore, finished 613 microns in diameter ~440 microns (0.613 mm -0.044 mm), through the analysis of interaction of machine and fan, which can meet the use requirements of different users.
