Structure and function of CLM vertical 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.It is composed of gearing with adjustable speed , rotor, guiding vane, shell body , cone filler for coarse powder, blower.
It is a kind of powder collector with high-efficiency , low powder consumption and convenience.
Roller is the main part to grins the materials into powder. It is equipped in the curving arm of the mill. In virtue of  the outside force, It pressed the materials on the table tightly. Driven by the mill table ,the roller runs, so the materials are grinded into pieces.

The mill table is fixed at the output shaft of the deceleration machine. At the upside of the table is the hoper with an annular groove in which the materials are grinded.
The pressurization device brings the grinding pressure. It contains oil pressure station, pull rod of hydraulic pressure for grinding.
Deceleration machine carries powder. The rotate speed of the mill table is the machine’s output speed.
According to the position of humidifier and dust collector. Our company can provide 2 allocation :three blower system and double blower system. This vertical grinder collect the finished products by whirlmind dust catcher. This configuration can reduce the working negative pressure and the volume of gas which through the dust catcher. In vertical grinder can use electrical dust catcher ,also bag dust catcher as terminal dust removal plant. By using the electrical dust catcher and bag dust catcher ,the gas can directly go from grinding into dust catcher. This construction can reduce the quantity of equipments and also simplify the allocation.

Working principles of the Vertical Mill CLM

The motor dives the grinding table to turn through the speed reducer. At the same time, 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 from the centre .The materials are crushed by the grinding roller when by pass of the groove on the grinding table. The crusher 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 airstream , 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.
