Osborn provides “unique” solution for opencast operation

Osborn reports that a R27-million order for a turnkey crushing and screening plant for a new mine in KwaZulu-Natal reflects its ability to deliver customised solutions that are a perfect match to customers’ requirements. According to Product Sales Manager Shane Beattie, this new plant features a unique process designed by Osborn to minimise fines generation in the produc-

be a jaw and cone configuration to crush down to a -80 mm product from a run of mine (ROM) of 600 mm. “We supplied an Osborn modular 3042 jaw plant feeding into an Osborn modular 2340 jaw plant, then over an Osborn modular 6 x 20 triple deck screen, splitting the product into -80 mm +30 mm, -30 mm +10 mm and a -10 mm +0 mm. “The primary reason for the two-stage jaw crushing process is to minimise the generation of fines (-10 mm),”Beattie elab- orates, adding that this material is a waste product. Beattie says that Osborn’s pioneering process is more effective than the conven- tional separation process at other plants, where all the ROM material is crushed to -1 mm and smaller, with flotation then being used to remove the impurities. “This process requires lots of water and waste that is more difficult to manage,” he says. Umzimkhulu and Rossmin will only pro- cess the high grade material, up to 99 % calcite. By only feeding the high grade -80 mm+30 mm to the tertiary/quaternary plant and, with the next stage being dry, the plant will produce a higher yield per ton crushed. “Since this stage is the most expensive part of the process, by only crushing the desired calcite, the operation will be able to dramatically reduce its cost per ton, and the capacity in this stage is uti- lised to its fullest potential.” Beattie says that Osborn’s attention to detail and commitment to meeting the client’s needs, together with the compa- ny’s long-standing reputation for quality machines and service, led to this signifi- cant order from Rossmin.

It has been supplied by Osborn to Umzimkhulu Industrial Holdings’ Rossmin opencast limestone mining operation at Port Shepstone. “The plant was designed and installed to only produce two sized products: 80 mm +30 mm and -30 mm + 10 mm. The -10 mm is a by-product,” Beattie explains. He says the process is revolutionary in that a conventional crushing plant would
