cement mill air flow

Volume flow measurement for regulating the air supply of

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.
