grinding mill load torque

  • TECHNICAL NOTES 8 GRINDING R. P. King

    A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power. The torque required to turn the mill is given by Torque T Mcgdc T f (8.9) Where Mc is the total mass of the charge in the mill and Tf is the torque required to overcome friction. Power 2 NT (8.10)
