    2020. 6. 1.· 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

  • Effects of mixtures of grinding media of different shapes

    2014. 6. 1.· 40 mm balls, 40 × 40 mm Eclipsoids and 32 mm cubes were used. The total load mass was kept constant for all grinding media shapes, as well as for the mixtures of grinding media for an average porosity of 0.4 (Austin et al., 1984).The grinding media shapes were used to grind 11 different mono-sized feed fractions of quartz with a specific density of 2.64 g/cm 3.
