This ConExpo-Con/Agg year yielded a multitude of new products offering everything from reduced emissions to increased productivity.

FLSmidth Salt Lake City, Inc.

Large feed opening

FLSmidth’s Raptor XL500 cone crusher features a large feed opening, high pivot-point crushing action, and wide crushing stroke. Its large 59.06-inch-diameter head and eccentric motion is said to allow feed up to 25 percent larger than crushers with less throw and similar head diameter. The crusher’s 148-inch diameter and 106,500-pound weight offer flexibility for multi-site crushing operations.

Telsmith, Inc., an Astec company

Advanced jaw crusher technology

Telsmith says its H3244 Hydra-Jaw, the largest model in its Hydra-Jaw Series, features advanced jaw crusher technology that offers lower operating costs, increased uptime and production capacity, streamlined operation and maintenance, and greater safety. The crusher’s 32-inch gape and 44-inch width is designed to accept larger feed; the Hydra-Jaw toggle provides hydraulic tramp iron relief with automatic reset, chamber clearing, and push-button setting adjustments. The unit can be mounted on portable plants or modular fixed-structure assemblies.

Terex Minerals Processing Systems

Easy clearing of jammed feed

The Terex Cedarapids MVP450X 400-horsepower cone crusher boasts major new enhancements, including high-speed clearing of jammed material, quick crusher separation capability for fast manganese changes, and easy-to-operate computer controls. The optional “Guardian” PLC control system optimizes production and is fully automated, according to the company. At the press of a button, fully guided dual-action tramp relief cylinders provide 6-inch lift for easy clearing of jammed feed material. The company says the hydro-pneumatic tramp iron relief system instantly resets the crusher setting after passing uncrushable material without having to activate valves and pumps. The hydraulic-powered threaded upper assembly allows for quick crusher setting adjustment under load.

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.
