"When the first Cavex hydrocyclone was introduced, the industry was changed forever," said Debra Switzer, Weir Minerals global product manager for Cavex hydrocyclones. In 1996, a team of engineers from Warman International got together to develop the "next big thing" in hydro- cyclones. "What they came up with was revolutionary," the company said. The truly unique 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 hydro- cyclones easily delivered up to three times the wear life of the old technology. 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 specialized dewatering hydrocyclones and superior rubber products for lining. This was significant for Cavex hydrocy- clones because it enhanced the portfolio and improved its wear rates. Last year, Weir Minerals introduced the Cavex 700CVX hydrocyclone, designed specifically to meet the customer demands. It has been proven to achieve up to 50 percent higher throughput capacity than other competitor cyclones in the 26-in. diameter range due to its larger inlet and vortex finder configura- tion, noted the company. Weir Minerals is set to redefine hydro- cyclone efficiency again with the development of the new Synertrex mon- itoring 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. Weir Minerals, Weir Minerals, Terex Finlay Tracked Inclined Screen Is Highly Versatile The Terex Finlay 674 is a "highly versa- tile and adaptable machine engineered and built for working in quarrying, mining, construction and demolition debris, topsoil, recycling, sand, gravel, coal and aggregate applications," according to the company. As a compact and easily transportable machine, it offers operators rapid set up and tear down times. The new screen- box features three inclined decks (top and middle deck: 12- x 5-ft., bottom deck: 10- x 5-ft.) giving a large screen- ing area of 170 sq. ft. The screenbox features quick wedge tensioning (top and middle deck), access holes and a bottom deck hydrau- lic tensioning system to reduce time required for mesh changes. All four discharge conveyors hydraulically fold for transport. The fourth product "over- size plus" conveyor can work at varying angles to accurately discharge material for recirculation and stockpiling. A high performance 42-in. belt feeder, with hydraulic variable speed drive, is standard and has proven performance and versatility in demanding and varied working environments. The hopper has a 10.50-cu.-yd. capacity as standard and can be fitted with a remote control hydraulic tipping grid. A Caterpillar C4.4 air-cooled engine is used to power the Terex Finlay 674. The heavy-duty crawler tracks, and optional radio remote control unit, make on site mobility very easy. The fully self-contained plant can be hydraulically folded and ready for trans- port in less than 30 minutes making it ideal for contract screening. Key features: • Triple deck screen with galvanized all around fixed catwalk access for ease of operation and maintenance. •  The fourth (oversize plus) conveyor can work at varying angles and can accurately discharge for recircula- tion to crusher or for stockpiling. •  Screen box angle can be hydraulically adjusted between 18 to 37 degrees. •  Maximum utilization of three decks provides ultra-efficient screening capabilities. •  Updated hopper and belt feeder gives improved material flow onto main conveyor.
