Jul 21, 2006 Abstract. A research team from the University of Utah is working to make inroads into saving energy in these SAG mills. In 2003, Industries of the Future Program of the Department of Energy tasked the University of Utah team to build a partnership between the University and the mining industry for the specific purpose of reducing energy consumption in SAG mills.
the mill power and the efciency of the mill operation Van Nierop and Moys, 2001. If a SAG mill has been designed with a conventional power or specic energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power consumption but will not satisfy
