Company Announcement - The new Cavex® 700CVX hydrocyclone from Weir Minerals can achieve up to 50% higher throughput capacity in comparison with competitor cyclones in the 26 inch diameter range, due to its larger inlet and vortex finder configuration. According to Sheldon Gabriel, product manager cyclones of Weir Minerals Africa and Middle East, the Cavex® 700CVX hydrocyclone has a small, more space efficient body, making it ideal for new installations. “It is also perfectly suited and sized to fit into existing cyclone clusters for easy retrofitting, adding substantially to increased capacity. This hydrocyclone is the result of extensive research and development by the company and underlines our philosophy of driving customer centricity in all product development.”

Mark Lockyer, Weir Minerals’ global product manager hydrocyclones, says that the need to increase throughput to maintain production levels is a reality for much of the 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.”

Gabriel says that Cavex® hydrocyclones have been highly regarded for their proven efficiency and high capacity performance for decades. Cavex® CVX hydrocyclones are designed to withstand severe abrasion caused by the rotational flow of solids and slurry. “The unique 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.”
Weir Minerals Africa is dedicated to ensuring its products maximise throughput both within current plants and in greenfield operations. The Cavex® 700CVX hydrocyclone is typical of the company’s commitment to best practice and is backed up by Weir Minerals’ extensive global service and aftermarket support.

The harsh African mining conditions provide particularly tough operating conditions for installed equipment, but this has been catered for with the Cavex® 700 CVX hydrocyclone, which features fabricated steel or cast ductile casing, replaceable elastomer liners up to 45 mm thick, ceramic lower cones, rubber lined steel vortex finders, rubber or ceramic spigots, rubber lined steel overflow pipe or air core booster caps.
