Abstract. Comminution in stirred media mills is a frequently applied top-down method towards the production of micron- and submicron particles. However, due to the high energy density, this type of mill is appropriate for mechanical activation (MA) as well. Despite the vast field of mechanochemistry which encompasses an increase in reactivity ...

In stirred media mills, there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1–6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10–40 lm.

Although wet stirred media milling has proven to be a robust process for producing nanoparticle suspensions of poorly water-soluble drugs and thereby enhancing their bioavailability, selection of bead size has been largely empirical, lacking fundamental rationale.
