Dynamic Behavior of Closed Grinding Systems and …

two reasons, grinding mostly is performed in closed circuits, where the product of the cement mill (CM) outlet is fed via a recycle elevator to a dynamic separator. The high fineness stream of the separator constitutes the final circuit product, while the coarse material returns back to CM to be ground again.
