Stirred media mills in the mining industry: Material ...

Stirred media mills. Efficient grinding of fine and ultrafine particles requires small media to increase the surface area and the consequent collision frequency, but ball mills are fundamentally limited in the momentum that can be applied to such small beads by the force of gravity, which sets a practical lower limit in media size.

Stirred Milling Technology – A New Concept in Fine Grinding

significantly increasing grinding efficiency. 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
