August 2016 www.coalage.com 67 suppliers news continued quisition of DSI's U.S. Mining Division by Jennmar has been fully consummated. As far as divestitures, which included Jennmar Australia, Jennmar Europe and Jennmar Latin America, DSI has elected to withdraw its proposal to the Australian Competition and Consumer Commission (ACCC) and both parties have decided to terminate the proposed transaction. Jennmar said it has no plans for divesting its very successful Australian operations and the company thanked its customers and employees for standing by them during these months of uncertainty. Jen- nmar will continue to deliver ground support options that are both commercially economical and safe to the Australian mining and tunneling industries. The divesture of Jennmar's European operations, which includes Jennmar Spain, Jennmar MultiTex in the Czech Re- public, Jennmar Merol in Poland, is now complete. Likewise, the divesture of Jennmar's Latin America operations ( Jennmar Chile, Jennmar Peru, Jennmar Mexico) is now complete. With regards to the RocBolt joint ventures, FCI and DSI continue to operate RocBolt Technologies Jining Ltd. (China), RocBolt Technologies Ltd. (South Africa) and RocBolt Resins Ltd. (Australia) as successful, stand-alone joint ventures. Weir Celebrates 20 Years of Hydrocyclone Excellence This month marks the 20-year anniversary of the first Weir Minerals' Cavex hydrocyclone. "When the first Cavex hydro- cyclone 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 in Australia got together to develop the "next big thing" in hydrocyclones. What they came up with was revolutionary. The unique inlet geometry removed all sharp angles from the feed chamber, allowing slurry to move through the hydro- cyclone smoothly, which greatly reduced wear while increas- ing its efficiency. The new generation of hydrocyclones easily delivered up to three times the wear life of the old technology. The streamline feed chamber is still in use today. The Weir Group acquired Warman in 1999 and in 2010, it acquired Linatex, which brought with it a range of dewa- tering hydrocyclones and rubber lining products. 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 hy- drocyclone, designed specifically to meet the demands of Weir Minerals' customers and which has been proven to achieve up to 50% higher throughput capacity than other competitor cyclones in the 26 inch diameter range due to its larger inlet and vortex finder configuration. "Product development never stops at Weir Minerals," Swit- zer said. "Over the past two decades, our team of engineers have developed advanced lining technology for ultra-heavy duty applications, to withstand the demands of high volume abrasive materials." Today, there are more than 26,000 Cavex hydrocyclones operating throughout the world.
