Pressure difference control is the key factor to improve product quality and output. Maintaining the stable pressure difference in the mill indicates that the dynamic balance between the amount of material in and out of the mill has been achieved, and the stable circulating load is the prerequisite for stabilizing the normal production of the mill.

Ball Mills - an overview | ScienceDirect Topics
The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.
