THE OPTIMISATION OF PEBBLE GRINDING
obtained by allowing a fraction of the feed to bypass the tertiary crusher. The aim of this work was to investigate the effect of pebbles size and mill speed on secondary grinding efficiency at a gold mine. Pebble mills are used at the mine for secondary grinding, using a pebble feed size of 65mm/35mm.
