    Vertical Roller Mill

    LM Vertical Roller Mill is one advanced mill, adopting top technology domesic and abroad, and based on many years' mill experiences. It can crush, dry, grind, and classify the materials. Vertical Roller Mill can be widely used in such industries as cement, power, metallurgy, stone industry, non-metallic mineral. Vertical Roller Mill is used to grind granular and powdered materials into powder with required fineness.

    Structure Of Vertical Roller Mill:
    The main structure consists of separator, roller, mill table, pressurization device, deceleration machine, motor, shell body, etc. Separator is an important part which determines the size of the final powder. Vertical Roller Mill is composed of gearing with adjustable speed, rotor, guiding vane, shell body, cone filler for coarse powder, blower.

    Vertical Roller Mill

    Application Of Vertical Roller Mill:
    Vertical Roller Mill specialized for the high production of superfine pyrophyllite powder making in glass fiber industry.
    Vertical Roller Mill specialized for the high production of gangue powder making in coal industry.
    Vertical Roller Mill specialized for the high production of various of stone raw material powder making in the stone industry.
    Vertical Roller Mill 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 Princeple Of Vertical Roller Mill:
    As chart 1 shows, motor runs under the condition that speed reducer drives the Nether millstone. The materials fall into the center of device through lock air feeder, and hot air comes into mill through air inlet. Under the function of centrifugal force, the materials move to the edge of the Nether millstone as it runs and rollers will grind the materials when they come by the annular chute. The grinded materials will be taken up by air circulation and the bigger powders will fall down for regrinding. Qualified powders will be collected by collecting device as to be final product. Materials containing water will be dried when they contact with the hot air. Different humidity materials can be dried to the requirement through adjusting the temperature of hot air. Adjusting the separator can get the required fineness powders.
