The Bond equation is used to calculate ball mill specific energy from T 80to the final product P 80size. The total circuit specific energy is the sum of the SAG mill and ball mill specific energies. W SAG= R (Ms+16000)/(Ms.447.3) (4) W T= K a . K b . W SAG . [10. BWi. (T 80 -0.5-1700-0.5). EF5] + W BM . K BM(5) Where: W

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. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates.
