2016-5-20  On the other hand, the wet stirred media milling studies from 2008 to 2015 referenced in Table 2 used horizontal stirred mills, and the use of vertical stirred mills for nanomilling of poorly water-soluble drugs is not as common. Also, a head-to-head comparative assessment of the two mill orientations appears to be complicated, if not impossible.

2010-7-20  In stirred media mills, particles as small as 10 nm can be achieved by stabilizing the particles appropriately. Surfactants (nonionic and ionic) as well as polymers have been used as common stabilizers . The stabilizer effect of ionic surfactants is due to the formation of surfaces with a charge sufficient for stabilization.

The possibility of grinding Al2O3 down to 10 nm in aqueous suspensions could be shown recently. Therefore steric and electrostatic stabilization mechanisms were adopted to avoid agglomeration processes during grinding process [1, 2, 3]. Based on these results the effects of changing the fluid from water to ethanol and the stabilization mode are investigated. Ethanol is a less polaric fluid ...

Stirred Milling Technology – A New Concept in Fine

2019-5-8  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.
