Grinding Mill Power

08-05-2017· Coming now to a study of the effect of the density of the grinding media upon the power required to drive a mill it follows that since the mass of grinding bodies has a definite configuration, as suggested by Fig. 3.3, then the torque to drive the mill will be proportional to the weight of the charge; that is, without powder, proportional to the density of the material of the balls or rods.

MILLING CONTROL & OPTIMISATION

ore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and
