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.

The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill ...
Cement mill grinding circuits using ball mills are used for grinding cement clinker into cement powder. They use about 40% of the power consumed in a cement plant. In this paper, we introduce a new Model Predictive Controller (MPC) for cement mill grinding circuits that improves operation and therefore has the potential to decrease the specific energy consumption for production of cement.
