Planetary ball mills often show shorter reaction times compared to mixer mills. This might be caused by the more frequent creation of new surface by the sheering motion as compared to the direct impact which rather compresses the powder present on the active surface. 23 It might also be the case that the higher energy input in planetary ball ...
