Stirred Mills Generation

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 …

The speed of rotation of stirrers in stirred mills is usually very high; about 25 m/s at the tip-ends. The motion creates high energy densities (about 300 kW/m3). The kinetic energy generated at such high tip speeds produces the energy needed for abrasion of fine mineral particles and therefore aids in size reduction.

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.

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.
