The effect of ball size on mill performance
1976-5-1 Pa. 17821 (U.S.A.) (Received September 10, 1975) 71 .SUMMARY The specific rates of breakage of particles in a tumbling ball mill are described by the equation S; = axa Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases- This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x,,, = h 1 d2_ The variation of a with ball diameter was found to be of the form a = k2jd1-5_ Both hl and h2 vary with mill
