May 01, 2014 It has generally been established by many researchers that grinding efficiency for a given size distribution is to some extent dependent on ball size , , , and from Ref. it has been established that ball diameter (d) relates to a and μ as follows: (14) a = K 1 d N 1 and μ = K 2 d N 2 where Austin et al. found that N 1 ≈ − 1 and N 2 ≈ 2.

The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.
