AMIT 135: Lesson 6 Grinding Circuit – Mining Mill Operator ...
For the full scale mill, specific power is multiplied by the feed rate to get the net mill power. This must then be increased by the anticipated mechanical inefficiencies (bearing/gear friction losses and possible speed reducer losses) as well as electrical losses, in order to arrive the gross mill power.

Mill speed is generally referred to as a percentage of critical, which is defined as the speed at which an infinitely small particle just follows a smooth shell lining in its motion. An increase in the mill speed will give a directly proportional increase in mill power but there seems to be a square proportional increase in the wear.
