Shear based stirred mill power model An adimensional. Stirred mill power has been modelled empirically, adimensionally and computational intensively through the use of the discrete element method and computational fluid dynamics. To this range of power modelling efforts, one more is added through the development of a shear based power for stirred

Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

Recently, Jankovic (2003) conducted grinding experiments using different types of mills and grinding media. For the vertical stirred mill, the results revealed that the most efficient grinding was obtained with coarse media (– mm) while the fine media were more efficient only for feed particles below 10 μm.

A combined computational fluid dynamics (CFD) and DEM other end. The high speed of the discs induces intense agitation approach was developed in the previous work to investigate slurry of the media (usually ceramic but sometimes sand) which in turn flow in a stirred mill (Jayasundara et al., 2009).
Micromechanical aggregate properties are correlated with stress conditions during the dispersion process in a stirred‐media mill. The fracture energy distribution of the aggregates measured via micro‐compression tests is compared with the stress energy distribution in a stirred‐media mill determined by CFD‐discrete element method simulations and by an analytical model.
In the present work two different stirred media mills (one with a cylindrical stirrer; one with a disc stirrer) and a planetary ball mill are investigated using coupled CFD (computational fluid ...

A CFD–DEM model was developed to simulate particle and fluid flow in a simplified stirred mill. The flow properties of different particles, mill loadings and rotation speeds and grinding media were investigated and compared with PEPT measurements under similar conditions.
Micromechanical aggregate properties are correlated with stress conditions during the dispersion process in a stirredmedia mill. The fracture energy distribution of the aggregates measured via microcompression tests is compared with the stress energy distribution in a stirredmedia mill determined by CFDdiscrete element method simulations and by an analytical model.
power models found in the literature followed by a general description of DEM and CFD stirred mill models as well as the insights that can be drawn from them. Finally, a generic stirred mill power model will be presented and applied to different stirred mill types in order to develop some insights into the differences between different mill types.
