SAG MILL DISCHARGE SCREENS-TROMMEL vs. VIBRATING

mill has a trommel on the discharge end of it. Oversize is returned to the mill by a bucket wheel and water jet. Trommel undersize was pumped to a vibrating screen where the screen oversize was sent back to the mill and the undersize was pumped to the cyclone circuit. Figure 2 shows the flowsheet for line 2 with only the trommel,
