Vertical roller mill is an energy-saving mill equipment that combines mature vertical grinding technology, successful foreign experience and technological innovation and upgrading of our company. It integrates crushing, drying, grinding, grading and conveying, and can be widely used in cement, electric power, metallurgy, chemical, non-metallic ores and other industries, and focuses on three major fields of non-metallic ores, pulverized coal and slag.
The Vertical Roller Mill integrating ultrafine powder grinding, grading and transporting has become a better choice in the ultrafine powder grinding industry.

The grinding plate rotates under the action of main motor of Vertical Roller Mill and the reducer. Meanwhile, hot wind enters the vertical mill. After raw materials fall onto the center of grinding plate, they move to the edge of grinding plate under the action of centrifugal force. While passing through the grinding area between roller and grinding plate, bulky materials are broken directly by the pressure of roller while fine materials form a layer where materials crush each other. Broken materials after grinding continue moving to the edge of grinding plate until they are brought away by the airflow at the air ring. For coarse materials which cannot be brought away would fall onto the grinding plate for another grinding. When passing the upper separator, materials in the air flow will be divided into two parts by the blades of rotor, that is, coarse particles and fine powders. Coarse particles would be sent back to have another grinding while the qualified fine powders enter the powder collector with airflow as finished products. For sundries like iron block in materials, when they move to the fringe of grinding plate, because of their heavier weight, they would drop to the lower cavity of grinding mill and next be sent into the discharging port by scarper installed at the bottom of grinding plate and finally be discharged out of the grinding mill.
