The stirred ball mill in this case demonstrates the ability to break the larger particles preferentially. This is more clearly evidenced by the nearly complete disappearance of particles larger than 10 ~m in Fig. 3(c) and (d). It seems that the feed material in each milling stage is processed as if it were going through a roll crusher.
