Engineering a total wear solution
Mineral processing plants cater for a range of commodities and therefore require different wear solutions . Older minerals-processing plants have often been designed with a specific type of wear material in mind , without due consideration given to its wear characteristics . “ The flow rate of the material through a chute or over a screen invariably alters over time as wear accelerates . If we are involved early in a project , we can predict these changes and deal with them down the line ,” says Sias Suurd , director at Rio-Carb .
“ When we engineer a solution for a specific requirement or application , we look at how it can be implemented elsewhere , which is of significant benefit to the entire mining industry as it strives to cope with the long-term problem of chute and screen wear , which impacts on productivity and maintenance costs .” Suurd argues that project houses have traditionally focused on cost , which does not always equate to the best solution . “ While chromium carbide ( CrC ) is a much more expensive material than quenched and tempered steel , for example , it has 10 to 12 times more wear resistance .
Rio Carb can engineer total wear solutions for specific applications and requirements .

Therefore , it is a far superior product , and we have a well-established track record in both its engineering and the correct installation of optimal solutions .”
“ There are a lot of mining operations that only look at the initial cost of the product and that do not perceive the long-term benefits and advantages . Our main challenge is to explain the role
that CrC can play in reducing the total cost of ownership . Minerals-processing plant operators have to ensure maximum productivity for the greatest period . This means that utilisation and availability are critical factors , which is where our total wear-solutions approach offers the greatest value proposition for our clients ,” Suurd concludes .
Skid steer loaders employed to clean ash slurry

Bovu Fluid Holdings is using a HPE Africa Hyundai HSL850-7 skid steer loader to clean ash slurry from ash traps and cooling towers at Eskom ’ s power station in Vanderbijlpark . According to Edward Bovu , owner of Bovu Fluid Holdings , this robust skid steer loader is perfectly suited for the tough task of removing ash slurry in confined areas at coal-fired power plants . The machine offers the operator excellent visibility and enhanced comfort to maximise productivity , minimise fatigue , and ensure safety on site .
Bovu says the highperformance skid steer loader , with a Tier 2 low-emission engine , provides sufficient power to handle any load .
