Abstract. herein, an innovative approach for determining the grinding media system of ball mill based on grinding kinetics and linear superposition principle was proposed. the optimal media ball size of −2 + 0.45 mm, −0.45 + 0.15 mm, and − 0.15 mm feeding samples were 40 mm, 30 mm, and 30 mm, respectively. according to the linear superposition principle, the media size ratio is equal to the yield of.
Approach is most frequently used in ball mill grinding circuits. the main advantage of this approach is the distributed control structure and its easy implementation.
