Understanding fine ore breakage in a laboratory scale ball

DEM models of fine grinding in ball and stirred mills have to date almost entirely focused on the motion of the media and their interaction with the mill configuration For SAG mills a large fraction of the feed material can now be accurately represented in DEM models However for other mill types with much finer feed materials such as the second chamber of a cement ball mill the vast
