Autogenous mill and semi-autogenous mill polysiususa

Autogenous (AG) and semi-autogenous (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 size-reduction systems.
