TECHNICAL NOTES 8 GRINDING R. P. King
2009-7-30 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.
