You can also design 10 mm, 11 mm or other diameters of steel balls. Small steel balls: 40 mm or 60 mm Medium balls: 80 mm Large steel balls: 100 mm or 120 mm Super large balls: 130 mm to 150 mm Theoretically, when the filling amount of steel grinding balls in the cylinder of the ball mill is 40%, the ball mill can obtain an ideal output.
smaller the ball size was, the smaller the crystallinity de-crease. As a result, using a small ball size can result in nanoparticles with greater crystallinity (Kim et al., 2019). Hlabangna et al. (2016 and 2018) discussed that the combining impact forces and abrasiveness between ore particles, grinding media, and mill boundary reduce particle ...
