Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product. They are suitable for both open- and closed-circuit operation.

In the stirred media mill, the boron nitride particles are stressed between the grinding media leading to a size reduction due to delamination of sheets and/or breakage of the particles. The number mean particle size measured by sedimentation analysis using a disc centrifuge decreases stronger with growing grinding time if larger ZrO 2 grinding media are …

Stirred media mills (frequently also termed attritor mills) provide an overall stronger increase in mass specific surface area and are thus used for fine grinding (Baláž et al., 2013, Juhász and Opoczky, 1990, Alex et al., 2014a, Alex et al., 2014b, Wang and Forssberg, 2006): in the liquid phase aggregation and welding of the particles can be prevented.

The polymerization of 1-vinyl-2-pyrrolidone (VP) mechanochemically initiated by grinding silica was investigated in a wet stirred media mill. The polymerization itself proceeds from the silica grinding without any additional initiator. We have found that the amount of grafted polymer increases with an increase in total ground silica surface.

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

Stirred media mill Comminution in stirred media mills enables the production of ultrafine particles down to the nanometer range. The grinding results are mainly determined by two contrary mechanisms: particle breakage and agglomeration of the so-created fragments. These competing phenomena often lead to a plateau in particle

Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to …

Grinding Power efficiencies are achieved by filling of charge and smaller steel media (balls) used for fine grinding. Typically, stirred media mills use 25mm make-up balls, where conventional ball mills are using much larger grinding media. The popularity of stirred media mills has risen in recent times.
