Different machines to meet all needs
For increased efficiency, the closed-circuit systems are widely used in cement grinding, in which the material exiting the ball mill is directed to the separator and divided into coarse and fine fractions. The coarse fraction is sent to the mill's inlet for regrind, whereas the fine fraction becomes the cement.
