Therer are different Solutions for Copper Ore Processing Plant, for example, CIP, CIL and Flotation Processing Plant, but the common processing is same, which means they all need crushing and grinding before separation, and usually use Ball Mill for the grinding purpose after grinding, the slurry will be subject to different mineral separators to collect the.
Data from ball mills with a wide range of diameters are analyzed using detailed mathematical numerical models. Analysis shows the relative power inefficiency of large ball mills is due to their inefficient breakage of coarse particles. The models developed can be used to scale up mill behavior. The behavior of large mills at Bougainville and Pinto Valley is compared.Processing at the Campbell mill is via three stage crushing and rod and ball mill grinding followed by gravity concentration to recover free milling gold, with refractory gold recovered by floatation. Flotation tailings are leached and flotation concentrate from both mills is treated by pressure oxidation at the Campbell mill.
Ball mill at the Asarel Medet copper mine. Pinion bearing damage in ball mill. Using HD measurement technologies, Bulgarian copper producer Asarel Medet AD monitors the mechanical condition of critical equipment in the open pit mine and flotation plant. This case study deals with the successful detection of outer race damage on a ball mill.Both ring geared mill drives and GMDs can be employed to drive autogenous, semi autogenous (SAG) and or ball mills. The applications may be the same, but the challenge now is to develop bigger drivetrains with the power to drive these larger grinding mills.
Mill diameter, mill length, grates openings, and pebble ports size the power equation is also function of all the operational variables selected for this study. The applied force is a function of the mass inside the mill and it is composed of balls, ore and water.
