What is the Stirred media mills?

Reply: Stirred media mills are usually constructed in the form of a cylindrical drum inside which there are a series of rods, arms or perforated discs which are rotated on a central shaft The drum is loaded with grinding media, such as metal balls or glass sand The media and the charge is ‘stirred’ together and thus the grinding takes place

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
