The crusher was run at a rate of about 30 tons per hour and 50 tons of the crushed material was processed by the mill circuit. "Commissioning a mill is a multistage process," stated Murray Nye, CEO and Director of Winston Gold. "The crushing and milling circuit are now being thoroughly tested and any issues will be identified and fixed.

Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.

Typically, pebble crushing also coarsens ball-mill circuit feed, a consideration if a ball-mill circuit is already taxed. The first case for pebble crushing, in order to compensate for decreased SAG grinding rates in the area between which impact or abrasion breakage dominates, deals with what is often referred to as the critical size .
