There is a mill dilution water line feeding directly into the feed hopper of the secondary mill that can be used to adjust the in-mill density as term %P
This study evaluated the performance of ball and vertical mills for secondary grinding of Mont Reed ore (P 80 of 53 μm), focusing on energy consumption, particle size distribution,
South Deep’s milling circuit consists of a single-stage semi-autogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball mills.
The Lubambe milling circuit utilises a primary semi-autogenous mill and a secondary ball mill in closed circuit. Milling circuit was commissioned in 2012 with a grate discharge arrangement in
