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.

Analysis of Power Draw in Ball Mills by the Discrete

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a

Analysis of power draw in ball mills by the discrete

Apr 01, 1999· The calculated power draft is maximum at about 50% ball load. According to Eq. 1, mill power is a function of ball mass (M b) and the distance between mill center and the center of gravity of ball mass (r g). So, as the mill filling increases M b goes up, but r g decreases. Therefore, the power draft passes through a maximum.

Mill power draw models SAGMILLING.COM

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.
