May 18, 2012 · Due to the rotation and friction of the mill shell, the grinding medium is lifted along the rising side of the mill until a position of dynamic equilibrium is reached, when the bodies cascade and cataract down the free surface of the other bodies, about a dead zone where little movement occurs, down to the toe of the mill charge

    Sep 01, 1999 · Two types of ball motion were considered for the determination of shear rates: cascading and cataracting. Cascading refers to the condition where the grinding media tend to roll down to the toe of the charge, whilst in cataracting the media are projected clear of the charge to describe a series of parabolas before landing on or about the toe of the charge

    In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods. Then another pilot scale ball mill with eight rectangle lifters is simulated again by both methods. The effects of lifters on ball shoulder and toe points as well as on creation of cascading and cataracting movements for balls are …
