Stirred mills are increasingly used in the mineral industry for a range of milling duties from fine to coarse grinding. This work investigated the particle and fluid flow in a stirred mill using a combined discrete element method (DEM) and computational fluid dynamics (CFD) approach.

#0183;#32;ConwayBaker et al. [] studied the effect of the impeller design on the media motion inside a vertical stirred mill by using Positron Emission Particle Tracking (PEPT).Three impellers were tested: a flat blade, a pin type and down pitched impeller. This work highlighted how the impeller strongly influences the upper and lower recirculation loops inside the mill, and consequently, the packing

In addition to the measurements the ball motion was simulated using a three dimensional Discrete Element Model (DEM). An attempt was made to account for mill feed via altered friction coefficients. Correlations of the DEM results and experimental findings at different operating conditions show a
2015. The Isamill is a horizontal stirred media mill used for fine and ultrafine grinding. Discrete Element Method (DEM) simulation has been used in this paper to study the behaviour of the media and the collisional environment in a full industrial scale Isamill.
#0183;#32;The present work takes advantage of a mechanistic mill model originally developed for ball mills and the discrete element method (DEM) to simulate breakage in a vertical stirred mill. Data from a batch mill, in which two materials were tested (copper ore and limestone), served as the basis for fitting selected material parameters, whereas the remainder were used as default.

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.
Table 1 Variable Used in Published Stirred Mill Power Models STIRRED MILL DEM SIMULATIONS The advent of the discrete element method (DEM) and its introduction to the modelling of mineral processes opened the door to exploring in yet greater detail the dynamics of these systems. This has been successfully demonstrated through modelling of
