     · Grinding balls were selected as shown in Table 1 for these reasons firstly it was observed that only balls smaller than 40 mm may show significant effects of media on grinding kinetics in small laboratory mills (20 cm diameters or smaller) secondly to mimic the charge motion in industrial mill the ratio of mill cylinder s diameter to maximum ball size should be at least 6 for instance the ratio was 8 in Bond ball mill work index test and Lee (2019) selected 25.4 mm balls
