role of cement mill in cement plant

Cement Separator. Cement separator, also called cement mill separator, is the necessary equipment in the powder classifying system of cement, chemical, mineral, and other industries. It can respectively collect the qualified fine powder and coarse powder from the airflow after they are ground by the grinding equipment to a certain extent.

Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions
