    Dec 01, 2013 In Fig. 3, as anticipated, at a given ball size, a higher rotation speed (rpm) yields a finer average particle size due to the higher number of rotations within a given period of milling time (12 h). Interestingly, at each rotation speed, there exists an optimal ball size at which the most reduced average particle size is achieved among other investigated ball sizes.Aug 15, 2012 ball mill rpm posted in Newbie Questions ok so I know this is a question I should be able to figure out on my own I thought I know of some web sites that had the equation but I must have been wrong any way the jar is 7.75 inchs wide and 10.5 inchs long and I`m using 50 cal round musket balls for media (it will be half full of media) so what rpm should I run it at Thanks so much.
