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 .
cement plant, the kiln. Based on their design, it is critical to keep the kiln in motion at all times when heated. The inching drive for this application is designed to operate whenever main power is lost for the rotation of the kiln. The second cement application for inching drives is the rotation of the horizontal grinding mills for maintenance.
