Experimental investigations and modelling of the ball …

 · 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 mill. Results suggest the possibility to ...
