# calculation for speed of ball mill of 21 rpm

Aug 15 2012 · ball mill rpmposted 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
