How we made our choices

When we ask readers how we can best help them keep track of changes in the products and services they use to produce aggregates, almost everyone wants an annual short list of the really important stuff.

No wonder. The sheer volume of introductions is overwhelming. Aggregates Manager covers dozens of products each year in its RollOuts departments and Supply Lines features.

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

Revolutionary multi-frequency screen

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.

Sandvik

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).

Metso Minerals

Increased production

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.

Atlas Copco

Increased feed capacity

Atlas Copco says its line of track-mounted Powercrusher mobile crushers and screeners includes four jaw crushers that incorporate “Quattro Movement” for maximum processing efficiency. Quattro Movement is made possible by an up-thrust toggle plate position. This causes a figure-eight motion in the moving jaw, which increases the feed capacity and produces a post-crushing effect as rocks exit the crushing chamber. Models include the PC 1055 J with a total weight of 34 metric tons and an output capacity of up to 200 metric tons per hour. The 40-ton PC 2 delivers up to 250 tons per hour. The PC 4 weighs in at 45 tons and provides up to 300 tons per hour. The 55-ton PC 6 has a double-deck independent pre-screen section just before the crushing chamber and delivers up to 350 tons per hour.

The unit’s screen box is 11 feet, 7 inches by 5 feet with a 57-square-foot screen area and is powered by a 100-horsepower Cat 4.4 engine. Four identical meshes are used on the screen to lower stock requirements.

Kleemann/Wirtgen America Inc.

Mobile impact crushing

The MR 110 Z EVO impact crusher from Kleemann features a new material flow concept — the discharge belt is 4 inches wider than the discharge chute which is 4 inches wider than the inner width of the crusher. The rapid flow of material keeps it away from the critical area under the crusher and reduces wear. Additional features include an independent vibrating double-decker pre-screen and a newly designed crusher bypass that includes changes to its geometry and form to boost performance and reduce wear. Optional new and improved screening units are available and are more than 44 percent larger in size than those on previous units, allowing for tonnages of between 350 and 450 tons per hour.

Screening and Crushing Solutions

World’s largest mobile cone crusher

Screening and Crushing Solutions says its TC1885 is “the world’s largest-ever mobile cone crusher.” The machine is powered by a 27-liter, 875-horsepower, twin-turbo, V12 Caterpillar engine.

Aggregates Manager’s Top 25 RollOuts for 2009

In a tough market, manufacturers respond with product introductions that offer streamlined features, greater efficiency, and better economy.

by Kerry Clines, Senior Editor, and Therese Dunphy, Editor-in-Chief,

How we made our choices

When we ask readers how we can best help them keep track of changes in the products and services they use to produce aggregates, almost everyone wants an annual short list of the really important stuff.

No wonder. The sheer volume of introductions is overwhelming. Aggregates Manager covers hundreds of products each year in its RollOuts departments and Supply Lines features.

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 2008 issue through the November 2009 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.

How we made our choices

When we ask readers how we can best help them keep track of changes in the products and services they use to produce aggregates, almost everyone wants an annual short list of the really important stuff.

No wonder. The sheer volume of introductions is overwhelming. Aggregates Manager covers hundreds of products each year in its RollOuts departments and Supply Lines features.

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 2007 issue through the November 2008 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.

Case Construction Equipment

Production-class wheel loader
