“When the first Cavex hydrocyclone was introduced, the industry was changed forever,” says Debra Switzer, Weir Minerals global product manager for Cavex hydrocyclones.
In 1996, a team of engineers from Warman International in Australia got together to develop the “next big thing” in hydrocyclones, and Weir Minerals claims that what they came up with was revolutionary.
The new inlet geometry removed all sharp angles from the feed chamber, allowing slurry to move through the hydrocyclone smoothly, which greatly reduced wear while increasing its efficiency. The new generation of hydrocyclones easily delivered up to three times the wear life of the old technology, says Weir Minerals.
The streamline feed chamber is still in use today. When Weir Group acquired Warman International in 1999, it brought with it a myriad of improvements and modifications designed to ensure Cavex hydrocyclones provide excellent wear life along with maximum productivity, regardless of the application.
In 2010, Weir Group acquired Linatex, which brought with it a range of highly specialised dewatering hydrocyclones and superior rubber products for lining. This was significant for Cavex hydrocyclones because it enhanced the portfolio and improved the hydrocyclone wear rates.
Last year, Weir Minerals introduced the Cavex 700CVX hydrocyclone, and has now developed the new Synertrex monitoring system. The latest technology in remote monitoring systems allows users to obtain operational data in real-time, to ensure optimum performance and efficiency of their mill circuit.
Today, there are more than 26,000 Cavex hydrocyclones operating throughout the globe, making up more than a quarter of the global market share.
