Mar 01, 2014 Though, there are small differences in the mill speed N 0.6 versus 0.7 and ball load J 0.5 versus 0.4, in our opinion the main factor is the ball size distribution a single size ball charge versus a ball charge made up of balls of three different sizes. The void space in the ball charge, the relative movement of different layers of balls ...
Ball Mills Mineral Processing amp Metallurgy. Working Principle amp Operation. The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill, for example a 5 x 5 Ball Mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball ...
