Results of Stirring Tests with Grinding Media. In order to evaluate the above equations for power consumption of grinding media in stirred mills, the torque to rotate impellers immersed in dense particulate media was measured as a function of several controlled speeds, impeller and tank dimensions, geometrical designs, and other relevant variables.
Scale Up in Sizing for Grinding Mills. Scaleup criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.
