Some investigations demonstrate that stirred mills (compared to ball mills) have better performance when grinding occurs on a micronscale . This improvement is because the mechanism of supplying energy during stirred milling is different from what happens in ball mills. In ball mills, the abrasive and impact stress lead to particle breakage.
