The Product output size is adjustable in the range of *******5 meshes.
Vertical grinding mill is a large scale equipment mainly used in metallurgy, construction,
chemical, mining industry etc. It is widely used for superfine grinding of non-metal ores, such as calcite, marble, limestone,coarse whiting, talc, kaolin, barite, dolomite, potassium feldspar, manganese ore etc.

Working Principle

When the mill starts to work, the main motor rotates the millstone through reduction box and the air gets into the mill through air intake. The material fall on the centre of millstone through screw feeder and move from centre to the edge of the millstone under the effect of centrifugal force. The materials are grinded by the rollers while moving across the grinding zone. The coarse particles are crushed and grinded directly whereas smaller particles form material bed in which mutual grinding takes place.

The grinded material keep moving to the edge of the millstone till they are swept away by strong air flow and the big pieces fall down to the mill stone for regrinding. The materials in the airflow passes through the impellor on the classifier above. The coarse powder goes back to the millstone again whereas fine powder goes out of mill and collected by cyclone collector. These collected powder is the final product of grinding mill.

The sundries for instance iron pieces mixed in the material moves to the edge of the millstone with the materials and falls down to the bottom part of the mill as they are heavy and cant be blown up. Then these sundries are scraped to the waste discharge opening and discharged out of mill.

The fineness of final product can be controlled by adjusting the rotating speed of the impellor in the classifier. The pressure in the rollers can be changed by adjusting the pressure of the hydraulic system to suit material of different hardness.
