As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a 50.8 mm/25.4 mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.
