The data Scale Up in Sizing for Grinding Mills. Scale-up 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.
