The Principle Of Vertical Roller Mill

[gjsohcat]

For non-metallic mineral materials with Mohs hardness below 7 and humidity below 6%, the vertical roller mill is widely used in electric power, metallurgy, cement, chemical, rubber, paint, ink, food, pharmaceutical and other production areas.

It integrates drying, grinding, grading and conveying. It has high grinding efficiency, low power consumption, large material size, easy to adjust end product fineness, simple equipment process, small floor space and low noise. It features small dust, easy to use and maintain, low operating cost and low consumption of wear-resistant materials.

Under the action of the pressure of the grinding roller, the material is crushed by the action of extrusion, grinding and shearing. The material after grinding is blown by the high-speed airflow at the wind ring, and the material with coarser powder will fall into the grinding plate for re-grinding, the qualified fine powder is ground with the airflow and collected by the dust collector to become the finished product.
