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 analysed. It should …
