Automated Sag Mill Speed Control Using On Contact

there are two lines consisting of this sag ball mill combination where the sags are denoted as SA and sa. note: each sag mill is operated in a closed circuit manner in conjunction with a typical trommel screen and pebble crushing circuit. the ball mills are also operated in a closed circuit employing two hydrocyclone separators. thethe 4.27 12.94 egl secondary ball mill is fitted with a 4125 kW motor and operates in overflow configuration. ball mill discharge slurry gravitates to the feed of the sag mill discharge screen situated above the mill discharge hopper. In 2002, the grinding circuit became sag mill limited by the competency of the mill feed. In
