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 "C-model" and should not be confused with the more empirical "D-model" that has a form similar to the Loveday equation.

In the mining industry blasts are usually designed to fracture the in-situ rock mass and prepare it for excavation and subsequent transport. The run of mine (ROM) fragmentation is considered good when it is fine enough and loose enough to ensure efficient digging and loading operations. Mining optimisation strategy is hence usually focussed on minimising …

thesis. The Morrell C-Model is a generalised tumbling mill model and is not specific to SAG mills. The model was adopted for use in the JK SimMet™ software package and this paper is based on the description in a JK Mineral Research Centre publication (Napier-Munn et al, 1996). The model contains too many equations and sub-equations to ...

The Morrell C model is a theoretical approach based on the dynamics of the grinding charge. By making simplifying assumptions about the charge shape, composition and position, Morrell developed analytical solutions to equations describing the the rate at which potential and kinetic energy is imparted to the charge during mill rotation.
