Johannesburg-based equipment manufacturer Osborn has been awarded a R6 million order for new crushers, including a modular jaw crusher plant from African diamond junior Lucara Diamonds for use at its Karowe mine.
The order reflects the continued success of the Karowe diamond mine in Botswana, where a number of exceptional diamond recoveries have made headlines, as well as the outstanding quality and reputation of Osborn machines.
Lucara’s flagship Karowe mine reported the recovery of “a spectacular Type IIa 336 carat diamond” in August, as well as a further three exceptional diamonds namely a 184 carat stone, a 94 carat and a 86 carat stone. A 12 carat pale pink diamond was also recovered.
The new Osborn machines form part of an expansion project at Karowe, says Osborn East Africa area manager Chris Slade.
Osborn secured this order from long-standing customer ADP Marine & Modular, which is supplying process and design services to the diamond mine, he adds.
Slade asserts that the quality of Osborn’s equipment contributed to this contract win. “Osborn modular crushing and screening plants have been supplied to clients in South Africa, as well as Lesotho, Guinea, Namibia, Zambia, Mozambique, China and Russia. They are making their mark around the world.”
He notes that customers are increasingly recognising the value of Osborn’s modular crushing plant, which, he explains, requires very little civil work. “Only a concrete slab is needed to stabilise the modular structure. It can be easily transported and re-assembled on site in a relatively short time.”
In addition to the 20 x 32 primary modular jaw crusher plant, Osborn’s order for Karowe also included a 12 x 8 secondary jaw crusher and two 24S gyrasphere cone crushers, for tertiary crushing applications at the mine. The scope of Osborn’s contract encompassed the supply and commissioning of all of the equipment.
