2020-9-24  INITIAL CONDITIONING OF NEW MILLS: Pebble or ball mill lined mills must be “ground in” to remove loose or excess material. It is best to use a cheap material, such as a charge of fine sand and 50% water, or scrap product with the media charge for this operation, followed by a through rinsing. The time required is usually 1 to 5 hours. If the mill is not clean after one treatment, the cleaning operation

The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit.
