Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating.

Data: There are three crucial inputs to the mill at the grinding facility: (1) the cleaned raw material (metal removed), (2) roll force to crack the raw material into target granularity, and (3) hot gases evaporating the moisture trapped in the material. To ensure high in-put quality, the settings and behavior of each subunit—like storage,
