Ratio of grinding mill loading by grinding balls. Ratio of grinding balls volume to mill working volume is calculated by the formula: where: G н – mass of grinding balls, kg; γ – apparent density of grinding media, kg/m3; L – drum length, m. Apparent density of grinding media depends on ball diameter and density of the material.
