Top 25 Rollouts of 2011
So each year, our staff reviews all the product introductions we’ve covered for the past year (our Top RollOuts “year” actually runs from the December 2010 issue through the November 2011 issue) to pick out 25 that we believe are worth further review. Our priorities are new concept products — which are rare — new series/new generation products in categories that relate to the aggregates industry, and other rollouts which serve our readers’ interests by increasing competition in a product category.
Inevitably, we omit deserving products, either because we just didn’t understand the significance of the product or because the announcing company didn’t communicate what was special about the product, or both. In either case, we apologize in advance for these omissions.
This year, we’ve added smart tags that lead to videos for many of the Top RollOuts. These videos include insights from the manufacturers and an explanation of some of the unique features. Go to http://www.gettag.mobi and download the free app, then scan each tag for more information.
KPI-JCI, a division of Astec Mobile Screens
KPI-JCI expects its multi-frequency screen to revolutionize the screening industry. With the combination of both conventional and high-frequency screens, the unit is able to maintain the higher production rates of a PEP screen at a lower angle, while handling higher moisture content materials. Coarser material requires more amplitude and less frequency, while finer material requires less amplitude and more frequency. The multi-frequency screen combines both theories. By working at a lower operating angle, the overall height of the screen is less — making it safer to work on and operate.
Sets new throughput standards
Sandvik says its QE440 scalping screen sets new throughput standards for the industry with over 40-percent greater screening area than the former market leader, the QE340. The 76,360-pound machine features stockpiling conveyors that are wider and higher for increased production capacity and larger stockpiling capabilities. The 53-foot, 6-inch unit is easily transported due to its hydraulic folding tail and side conveyors and its fully tracked chassis. Additional features include a screening surface 40 percent larger than its predecessor; and stockpiling conveyors in three sizes — oversize (5 feet, 3 inches wide and up to a 13-foot, 7-inch discharge height), mid-size (3 feet wide and a 13-foot, 11-inch discharge height), and fines collector (3 feet, 3 inches wide and a 13-foot, 8-inch discharge height).
While banana screens are said to offer 40 percent more production on the same footprint as a typical incline screen, Metso says its Ellipti-Flo screening system is expected to increase production by an additional 30 percent over the banana screen. Designed to handle separation of traditionally challenging material such as wet, sticky feed, the system also has high-load, bearingless exciters.
