Ball Mill Motor Power Draw Sizing and Design Formula

  • 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.
