Unlike tumbling mills, where comminution occurs from both impact and attrition grinding, in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (Napier-Munn et al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur.
