Chat MoreExample a mill measuring 11 0" diameter inside of new shell liners operates at 17.3 rpm. Critical speed is. C.S. = 76.63 / 11 0.5 = 23.1 rpm. Ball and SAG Mills are driven in practice at a speed corresponding to 60-81 of the critical speed the choice of speed being influenced by economical considerations.
Chat MoreBall milling is one of the few unit operation that improves with increasing mill diameter. If acceptable results can be obtained with a 12" jar mil then good result will certainly be obtained with a 72" diameter mill. Of course there is the possibility of over milling obtaining a different particle size distribution or a need to change
