Energy Efficient Large Capacity Vertical Slag Vertical Mill Cement Grinding Roller Mills
Description:
Vertical roller mill is widely used in the raw material grinding process. Raw materials input grinding table and are crushed and pulverized on it and transported to separator by kiln exit gas introduced into the mill as drying, transporting and separating purpose. The material can be: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble , mineral , ore and etc.
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when it passes through the annular groove on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.
