    Analysis of power draw in ball mills by the discrete

    But as themillspeed approaches the critical value more number of balls start to stick on themillshell, the effectiveballmass reduces and thus, themilltends todrawlesspower. In this context, one should realize that the peak of the curve would depend upon friction betweenmillshell and grinding media.
