2003922· The earliest analysis of ball motion in tumbling mills dates back to early 1900, when Davis (1919) calculated trajectories of a single ball based on simple force balance. Rose and Sullivan (1958), while reviewing the work relating to charge motion, emphasized the need to consider the frictional factor, which was neglected up to that point.
