Nanoparticle Production with Stirred‐Media Mills ...

16/08/2010  Nanoparticles can be produced by wet grinding in stirred‐media mills. In the lower nanometer range a true grinding limit exists, where the transferred energy from the grinding media is no longer sufficient to induce further breakage of the particles even after stressing events with high stress energies. Variations in process conditions lead to the conclusion that the grinding limit is hardly ...

Stirred Milling Technology – A New Concept in Fine Grinding

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. The bead size is small, typically 1 to 6 mm which means a ...

- In stirred media mills, only a small portion of the energy invested in the milling process is used to grind the particles. Most of the energy is transformed into heat because of several processes (e.g. deformation of the grinding media and friction). It is important to optimize the process to minimize the amount of energy invested and to reduce the wear of the grinding media (Faes Kwade ...
