The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
The no load power is a measure of some of the power losses in the gears, bearings and electrical components and is the gross power draw of the mill when empty, obtained either during commissioning of the mill or when ground out for a mill reline. Morrell [13] developed an empirical expression for the no load power draw of ball, SAG and AG mills as
