For the mining industry, our semi autogenous grinding mill uses a minimal ball charge in the range of 6 15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Of all the costs that are associated with mining, cement industries or power plants, comminution of materials accounts for the majority. Comminution costs constitute mainly electricity, grinding media and liners. Of these three components, Grinding Media form the major portion of the consumable costs and can be as high as 40% 50% of the total.
The grinding circuit consists of a ball mill 2.9 metres in diameter and 3.7 metres long serving as the primary grinding mill. Two secondary mills, 2.7 metres in diameter and 2.6 metres long, complete the grinding to 80 percent passing 200 mesh. The grinding mills operate in closed circuit with hydrocyclones.
Tails from the flash flotation cells are recycled back to the ball mills for further grinding. The target final product grind size from the milling circuit is 80% passing 150 µm, although increased throughput rates in 2011 and 2012 resulted in grind size P80 coarsening to 170 to 190 µm at times.
The apparent difference in capacities between grinding mills is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5 x 5 Ball Mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball mills designated as 5 x ...
