Two types of mills commonly found in the minerals processing industry are ball and semiautogenous (SAG) mills, which use both ore and steel balls as grinding media (Wei and Craig, 2009b).In the case of a ball mill the ore is crushed before it enters the mill, whereas a SAG mill receives runofmine (ROM) ore directly (Stanley, 1987).A SAG mill in a singlestage closed circuit configuration ...

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 ...

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.
