Weba Chutes Systems secures contract for Marikana operation

Weba Chutes Systems, a manufacturer of custom engineered chute systems, has secured a contract to supply four chutes to Sibanye-Stillwater’s Marikana operation in South Africa. These systems will replace existing conventional chutes that have been

underperforming and failing to meet the required standards set by Sibanye-Stillwater. The four surge bin discharge chutes supplied by Weba Chute Systems will be responsible for feeding UG2 ore with a chrome content of 25% onto a vibrating feeder at the Marikana operation. The vibrating feeder operates at a peak capacity of 250 tons per hour, conveying fines with a maximum lump size of 90 mm and a bulk density of 3.8t/m³. According to Dewald Tintinger, Technical Manager at Weba Chute Systems, the existing conventional chutes at the concentrator had been causing frequent blockages as well as exhibiting high wear, both of which were unacceptable. “As always, when faced with such situations our objective is to custom-engineer a chute system that will address these issues and consistently perform according to the required specifications in the long term,” he says. While Weba chutes have been applied primarily in the mining industry for the transfer of materials such as copper, gold, iron ore, diamonds, coal and platinum, the company has noted a growing demand from other sectors including aggre gates and sand quarrying, power generation, steelmaking, cement production and food processing. 
