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 For mills of different diameter but running at the same fraction of critical speed and having the same fractional filling Net power
