16.5 ft ball mills with an ef ciency of 0.88. a study carried out by the author in 2004 on the worsley alumina rodball circuit line no 1, showed ef ciencies of 1.27 for the rod mill and 0.67 for the ball mill. the particle size distributions reported are shown in figure 1. it follows that the
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. rod and ball mills by c.a. rowland and d.m. kjos allis
Ball mill operating principles, ponents, uses . ball mill the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size the large balls tend to break down the coarse feed materials and the smaller balls help to form he fine product by reducing void spaces between the balls ball mills grind material by impact and attrition
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.
