Optimum choice of the make-up ball sizes for maximum ...
The overall S values for all make-up ball size classes are given by the weighted sum (12) S ¯ i = m 1 * S ¯ i 1 + m 2 * S ¯ i 2 + ⋯ here, m 1 ⁎ is the mass fraction of balls present in the mill that derived from make-up balls of diameter d 1 under the equilibrium condition, m 2 ⁎ is that derived from make-up balls of diameter d 2, and ...
