Coupled DEM-CFD Model to Predict the Tumbling Mill Dynamics

Coupled DEM-CFD Model to Predict the Tumbling Mill Dynamics Conclusion The complex three phase flow can be modelled efficiently using coupled DEM-CFD model. The pure DEM model can effectively predict the particle flow but it generally over predicts as the effect of shear forces from the slurry is not accounted for. The pure CFD model fails to predict the free surface profile of the slurry

Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
