Morrell Cmodel
Applies to both SAG and ball mills, with variants for gratedischarge and overflow mills. This model was developed as part of the PhD thesis of Stephen Morrell at the University of Queensland and is the model used in the JK SimMet software for determining mill power draw. It is described as the "Cmodel" and should not be confused with the more empirical "Dmodel" that has a form similar to ...
