The 28 MW mill will be 12.2 m in diameter with an effective grinding length EGL of 8.2 m. Ball milling will be accomplished in a single 22 MW, 8.5 m diameter, 13.3 m EGL effective grinding length ball mill. It will be fed by a combination of SAG mill cyclone underflow and recirculated ball mill cyclone underflow.
Once up and running, the Kansanshi Mine expansion and the Sentinel project in Kalumbila under the FQM& 39;s Trident Mining project would consume 50, 000 tonnes of mill balls yearly.
Ore is crushed in-pit, in three semi-mobile gyratory crushers. Overland conveyors feed two secondary crushers, and two mill trains each consisting of a 40 foot diameter 28 megawatt SAG mill twinned with a 44 foot length 22 megawatt Ball mill. The grinding mills are amongst the largest of their type currently operating in the world.
