Weba Chutes Save in Western Australia

An important factor in Weba Chute System’s design
process is chute inlet configuration, as depicted here.

Rio Tinto’s Paraburdoo mine extension project in Western Australia has reported significant savings in maintenance and operating costs following installation of two transfer points by South African company Weba Chute Systems. Productivity at the mine has risen sufficiently that Weba Chute Systems is negotiating for future deliveries that could ultimately replace all the transfer points.

The two main transfer points already replaced handle up to 300-mm material on the incoming 4,000-mt/h mine conveyor and direct it through 90° into the processing plant. Weba customdesigned these two transfer points by examining belt width and speed, as well as material size and shape and throughput, and then processing this data. “In many instances we are able to recommend additional cost-savings. This makes for a value-adding, applicationdriven approach that maximizes customer benefits,” said Werner Baller, managing director of Weba Chute Systems. The South African specialist has installed similar transfer points at Kumba’s Sishen iron ore mine in South Africa’s Northern Cape province that have been operating successfully for the past decade. Rio Tinto personnel from Australia have visited Kumba in order to see the chute systems in operation.

“Our initial success at Paraburdoo is being observed keenly by the global bulk materials handling industry. It is also an important benchmark for our Australian operations, in addition to buttressing our global standing as a leading innovator in bulk materials handling technology,” said Baller.
