A DEM based scale-up model for tumbling ball mills
A simulation started with the formation of a packed bed of the balls and powders in a still mill (Fig. 1 a).The mill then rotated at a given speed to lift the ball-particle mixtures (Fig. 1 b).After the flow reached the steady state as shown in Fig. 1 c (by monitoring flow velocity), the flow dynamics information was then collected and …

The truth about population balance modeling
This wet ball mill model, comprising the assumed breakage function, solids residence time assumed to be that of liquid, and back-calculated breakage rates, works quite well in circuit simulations. All three individual elements, however, are false. The model cannot be used to assess changes to the mill itself. While shrouded from proper vetting ...
