SABC Grinding Circuit
The SABC circuit design is to accept minus 8″ run of mine ore from a 12,000 ton silo. Two Forano pan feeders discharge from the silo onto a 48″ belt which feeds the 32′ x 13.5′ mill. The mill is powered by two 5500 hp D.C. motors. Nominal mill speed is 10.7 r.p.m. (78% critical) with a top speed of 11.3 r.p.m.
