Optimum choice of the make-upballsizes for maximum

For a single size of make-up balls, the ball size distributions exhibit a mono-modal size distribution with a mode close to the original make-up ball sizes. A 1:1 mixture of two make-up ball sizes shows the bimodality of the ball size distributions, consisting of two populations derived from large and small make-up …

However, as a group, they are not entirely satisfactory because the optimum mixture of balls depends on the feedsizeas well as the productsize. Further, theball size distributionin themillis not a simple parameter that can be controlled directly, as it depends on the make-upballcharge and wear rate.
