CFD MODELLING OF A STIRRED BEAD MILL FOR FINE

CFD modelling has been developed for a laboratory-scale Netzsch horizontal bead mill. The details of the internal geometry including the rotor with attached discs are modelled using a multi-block body-fitted finite volume method. The mixture of grinding beads, fine product particles and water are treated as a single fluid, and the equations of conservation of mass and momentum are solved ...

CFD‐Discrete Element Method Simulations Combined with ...

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.

01/06/2020  The Bond ball mill work index is inappropriate for use with stirred media mills, since it is a dry test, and involves stress intensities and forces that are dissimilar to what a stirred mill experiences. Additionally, the Bond grinding law usually does not hold for finer sizes typical in these applications. Industry therefore uses several open circuit batch grinding tests on laboratory scale ...
