A significant challenge when modelling grinding mills is to separate the characteristics of the ore from the characteristics of the grinding environment (Powell and Morrison, 2007). This is especially true for models of the breakage rate as the models have to represent the full range of operating conditions given by the grind curves.

Highlights Ore effects on the product shape were studied in order to monitor breakage events in SAG mill. The quantitative shape properties were fitted well to the 3parameter lognormal distribution. An increase in ore strength corresponds to a decrease in product size, angularity and elongation. By increasing ore hardness, the main breakage event changes from impact to attrition and abrasion ...
