Conceptual Model Of Ag/sag Operation For Operator Training

For many years mill operator training was an informal process which involved senior operators training junior operators on an as-needed basis. The more rapid incorporation of new processing and information technologies, the goal to keep labour costs to a minimum by doing more with less, and the complexity of AG/SAG mill operation has forced companies to have a closer look at operator training. This paper describes a conceptual model of the charge of a AG/SAG mill that can be used for operator training. The conceptual model divides the charge into three regions: cascading, cataracting and toe. Mill behaviour is explained by the changes that occur in each region.
