For increased efficiency, closedcircuit systems are widely used in cement grinding, in which the material exiting the mill is directed to a separator. The coarse fraction is sent to the mill's inlet for regrind, whereas the fine fraction becomes the cement which is conveyed by belt or powder pump into silos for storage.
