A method for simulating the motion of balls in tumbling ball mill under wet condition is investigated. The simulation method is based on the three-dimensional discrete element method (DEM) and takes into account the effects of the presence of suspension, i.e., drag force and buoyancy.
The Herbst and Fuerstenau ball mill model was implemented in the software Integrated Extraction Simulator (IES), owned by Orica, to perform all simulations. Briefly, Herbst and Fuerstenau (1980) proposed describing milling on the basis of energy rather than time, so that the population balance model formulation is as described as: (1) d ω i …

Research Highlights No considerable influence of speed ratio k in the range − 3 < k < − 1 on the grinding ball motion pattern was observed. Grinding ball motion is strongly affected by the friction arising, among others, from different feed materials. Friction necessarily has to be considered in studies on stress conditions in the planetary ball …
