Stirred Mills are becoming increasingly used for fine and ultra-fine grinding. This technology is still poorly understood when used in the mineral processing context. This makes process optimisation of such devices problematic. 3D DEM simulations of the flow of grinding media in pilot scale tower mills and pin mills are carried out in order to
spectrum of similar performance vertical stirred mill and ball mill were predicted using the discrete element method and predictions of breakage rates of the different size reduction machines using the UFRJ mechanistic mill model confirmed the higher efficiency of vertical stirred mills, as has been observed in industrial practice.

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. The simulations are likened with a
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

The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

Discrete Element Modeling is a very powerful technique to simulate granular materials. But, they are computationally expensive. As the computers become faster and more cores can be added to a chip, DEM calculations would become faster due to ease of parallelization. Results provide incredible insight into
