Weir Minerals stated that its Cavex 700CVX hydrocyclone can achieve up to 50% higher throughput capacity in comparison with other competitor hydrocyclones in the 26in (660mm) diameter range due to its larger inlet and vortex finder configuration.
The Cavex 700CVX hydrocyclone also provides a higher throughput than the Cavex 650CVX hydrocyclone from Weir Minerals, in a smaller, more space-efficient body, making it ideal for new installations. It is also perfectly suited and sized to fit into existing hydrocyclone clusters for easy retrofitting to increase capacity.
Mark Lockyer, global product manager, hydrocyclones at Weir Minerals, said: “The need to increase throughput to maintain production levels is a reality for much of our industry, with many mines having to process more ore than they have in the past. In these conditions increasing throughput is essential. Sites that can achieve higher throughput with minimal capital expenditure certainly have a competitive advantage.
“Cavex hydrocyclones have been highly-regarded for their proven efficiency and high capacity performance for decades. We are committed to ensuring our products stay in step with our customers’ needs, which means developing solutions to maximise throughput both within current plant set-ups and in greenfield operations. The Cavex 700CVX hydrocyclone delivers on this commitment, and like all our products is backed up by our extensive global service and aftermarket support.”
Cavex CVX hydrocyclones are designed to withstand severe abrasion caused by the rotational flow of solids and slurry. The shape of the Cavex hydrocyclone range features a laminar spiral inlet geometry that allows the slurry to follow a natural path without encountering any shelves, edges or corners. This reduces turbulence inside the hydrocyclone, which helps maximise separation efficiency, hydraulic capacity and wear life, while minimising localised wear in the feed chamber and vortex finder.
Other features of the Cavex 700 CVX hydrocyclone include fabricated steel or cast ductile casing, replaceable elastomer liners up to 45mm thick, ceramic lower cones, rubber lined steel vortex finders, rubber or ceramic spigots, rubber lined steel overflow pipe or air core booster caps.
