Some examples of medium speed mills include vertical spindle bowl mills, vertical roller mills, and ring and ball mills. The operation of these mills, as described by Rees and Fan [5], is presented here. In such mills, raw coal enters the mill from an inlet pipe, and drops onto a table or bowl rotating at a constant speed.
Uniform flow of feed to the mill for stable mill operation Low ingress of false air to decrease fan kW usage and cost. The sluice handles all new feed andmaterial coming from the externalcirculation system. For normal raw mills this material flow accounts for 115150% of the new feed rate; for bigger mills it can represent more than 1,000 t/h.

The increasing use of vertical roller mills (VRMs) in the production of cement to reduce power consumption and CO 2 emissions has resulted in an increasing need for VRM optimisation. As cement producers look to protect profits as well as their environmental reputation, a process audit can identify the root causes of issues to help plan for improvements in power consumption and performance.
