May 15, 2015 In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.

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.

Aug 02, 2013 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
