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.

EF1 Dry grinding - for the same range of work as wet grinding, dry grinding requires 1.3 times as much power as wet grinding. EF2 - Open Circuit Grinding - when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
