Experimental investigations and modelling of the ball ...

2011-9-15  In order to characterise the stress conditions in planetary ball mills, detailed information about the motion patterns of the grinding balls present in this mill type is needed. The grinding ball movement varies depending on the mill operating parameters, including ball type and size and feed type and size, so these have to be considered carefully.
