Autogenous (AG) and semiautogenous (SAG) mills have been used for over 20 years for the coarse grinding of diverse ores (including gold, copper and iron ores). They offer advantages with regard to capital costs and operating expense compared to the secondary and tertiary crushers used in conventional sizereduction systems.

to mimic the grinding mechanisms observed in industrial units. The best examples of this can be observed in the Bond series, where ball mills, rod mills, and crushers are tested using similar laboratoryscale apparatuses. Similarly, the MacPherson and media competency tests were designed to mimic autogenous grinding mechanisms.
