Ball Mill Motor Power Draw Sizing and Design Formula

2020-10-29 · The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 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.

Report on Ball Sizing. Ball sizing, also known as ball broaching or Ballizing, is the process of forcing an oversize ball through the inside diameter of metal part.It will increase the inside diameter and greatly improve the surface texture of the part. Under ideal conditions, tolerances of one or two ten-thouhs of an inch and a mirror like surface can be achieved.
