2021年9月1日 Cataracting or impact grinding is more pronounced in AG/SAG grinding mill, where the charge materials are elevated by the lifter to a height until the gravitational force of the charge reaches equilibrium, hence falling to the toe angle of the mill (Owen and Cleary, 2015). In such a process, the charge assumes a parabolic geometry or trajectory.
