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 material’s requirement, and also through adjusting separator , it can reach proper fineness of materials.

  • Performance Characteristics
  • Product Parameters
  • Low running costs

    It 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 from the work, and the roller and liner are made with quality components, it is of less wear and long life.

  • Simple and reliable operation

    Its automatic control system can reach remote control, and that 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 protection

    It capabilities small vibration, low noise, and sealing device being a total, and the system also works with no pressure and dust spills.
