Vertical coal mill manufacturers in China

Vertical mill is a versatile mining equipment, and can grind coal, so it is also named vertical coal mill.

Vertical mill is widely used in mining, chemical ,metallurgy industry, and it can grind the carborundum, zirconite, quartz, granite, barite, marble, limestone, talc, gypsum, slag, porcelain, glass and other more than 200 kinds of non-explosive, non-flammable minerals that Moh's hardness is below 9.5. The final products can be adjusted between 0 and 2.8 mm as required.

Working principle:
The motor dives the grinding table to turn the through the speed reducer.
At the same tim, hot air comes into the roller mill from the air inlet.
The materials fall down the centre of grinding table from the feeder.Because of the centrifugal force, the materials move to the edge of grinding table form the centre.
The materials are crushed by the grinding roller when by pass of the groove on the grinding table.
The crushed materials continue to move to the edge of the grinding table until taken away by the airstream.
Then the bigger materials fall down the grinding table and the process of crushing continues When the materials in the airstream pass the separator on the top of the mill the materials fall down the grinding table from the taper filler under the force of guide leaf blade .
The fine powder comes out with the airstream，and is gathered by the dust catcher of the system The powder gathered is the final product of roller mill. In the process of the contact of ai rstreamy.
The materials are dried to meet the clients’ need at the proper moisture. Through the adjustment of the angle between the separator and the leaf of wind’s direction(not suitable to the small type of vertical mill)，and also the speed of the separator rotor，it can reach the proper fineness of the materials.

SBM is a manufacturer of mining machine of China, and supplies all kinds of crushers and grinding mills.
