In a cement plant, the air flow to a raw mill is monitored. The objective of this monitoring is to achieve the highest possible efficiency of the raw mill. Controlling the supply air to such a vertical mill can also lead to considerable energy savings, as the maximum air volume does not always have to be used, but can be adapted to the process.

Primary roller mill controls are: Mill drive power or mill differential pressure to control mill feed rate. Inlet gas temperature. Outlet gas temperature. Outlet gas flow.
