    2020-6-1 · The existing SAG Mill Discharge screen had a single deck design of 3.6m x 8.5m and handled less than 1,900 TPH when screening at 13mm. This quickly became the process limitation. In an attempt to assist the movement of material off the deck and reduce the frequency of overloads, the customer decided to incline the screen and upgrade the drive.

    2013-12-22 · I’ve got to explain this a little bit. This flowsheet is typical of lines 1 and 3. The SAG 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

    2014-10-1 · MW). It has been the industry standard for SAG mills above 13 MW capacity. However, pinion systems to 8 MW per pinion and dual motor systems with quadruple pinions extend the range of gear driven mills to a theoretical limit of 32 MW. The Ernest Henry SAG mill (11 MW) is currently the largest twin pinion single drive mill installed in Australia.

  • SAG Milling in Australia -Revised Submission

    2014-10-1 · Developments in SAG Mill Design and Operation Over the last few years, SAG mill manufacturing technology has advanced rapidly. The bounds of mill size have been pushed from two directions. Firstly, the advent of ring motors has removed the constraint applied by the power that a single pinion gear was able to transmit.

The SAG mill discharge is cycloned, with a cut 80% less than 75 µm, the underflow passing to a ball mill (4000 x 6000 mm, 1.4 MW), with the cyclone overflow joining the ball mill discharge. The combined ball mill discharge is then cycloned
