Stirred Media Mills

Agitated media mills – Making

Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.

A cell-based PBM for continuous open-circuit dry milling ...

The fitting of the RTD using the cell-based PBM reveals that stirred media mills have much higher R, on the order O(10 0), than the continuous tumbling ball mills O(10 −3 −10 −1). The cushioning action (nonlinear breakage) of the finer particles leads to a coarser product than that predicted by the traditional linear PBM.

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.

Grinding Mills and Their Types – IspatGuru

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.
