Vertical Grinding Mill - China

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. Specification:
