Top RollOuts of the Year 2009
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.
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.
High shear, natural attrition
McLanahan Corp. says its “ultra-clean” attrition scrubber uses radial and axial turbines to create high shear and natural attrition to address sand equivalency and durability problems in natural construction sands, as well as for surface cleaning of mineral sands and in soils washing applications.
Michelin says its XHA2 loader tire features additional rubber in the tread to make the tire more damage resistant; sidewalls strengthened with a special protective rib and anti-scrape shield; and crack-absorbing rubber compounds to help prevent flats. The tire is said to last 9 percent longer than its predecessor.
Choose diesel or electric power
Powerscreen’s dual power screen gives users an option of diesel or electric power to help avoid high fuel costs and address environmental concerns about diesel emissions. Once positioned on site, the unit can be switched to operate on electricity. The track screen retains all the benefits of a mobile machine.
Wheel loader simulator
Vista Training’s interactive, PC-based training simulator for wheel loader operators puts raw trainees or experienced operators at the controls of a modern wheel loader in a virtual quarry. The Wheel Loader Personal Simulator offers eight lessons of increasing difficulty. Commercial software licenses start at $6,000.
Screens and Screen Media
Durex Products, a division of Linatex Corp. of America, says its Armor Screen combines wire cloth with a molded coating of polyurethane. The polyurethane coating provides relief-tapered openings to increase throughput and reduce plugging; the woven wire backbone creates a wear-resistant liner.
Astec Mobile Screens
Mobile, versatile screen
Astec Mobile Screens says its new Multi-Frequency Screen allows for flexible sorting diameters and frequencies. The screen integrates conventional and high-frequency screen movements, applying more amplitude and less frequency for coarse materials, and less amplitude and more frequency for finer materials.
Easy panel changes
Metso says its new LS HiPer Flow screen panels are made of high-quality, open-cast polyurethane and offer up to 30 percent more effective open area for increased throughput. The panels are lightweight and self supporting for easier panel changes and attach to existing competitive modular screen decks.
Customized screen deck
W.S. Tyler says its new TAGG Screen is the first vibrating screen designed specifically to meet the screening demands of the aggregates industry. The screen offers tailor-made deck configurations and a choice of wire or polyurethane cloth, with delivery in five days.
New wheeled excavator
John Deere has rolled out the 51,368-pound 220D wheeled excavator. The new 159-horsepower, Tier 3 excavator features wide axles and additional weight for more stability and lift capacity. Its digging depth is 20 feet, 8 inches.
Proven performance for Cat’s new mining trucks
Caterpillar says its new F-Series mining trucks with C175 16-cylinder diesel engines meet U.S. EPA Tier 2 emissions standards. The 793F mechanical drive truck boasts a faster speed on grade for 5 to 10 percent more productivity than the 793D. The cab features enhanced ergonomics and easy-to-access controls.
Purpose-built Kawasaki takes on an additional loader size class
Kawasaki’s 92ZV-2 wheel loader features dual Z-linkage for high breakout force; heavy center pins; rubber gasket-sealed front glass; and extended bumpers to protect battery boxes. Cab features include an adjustable declutch and dual-boom kickout control, idle management system, and dual-mode engine switch.
Volvo Construction Equipment North America, Inc. says its new EW230C wheeled excavator’s design ensures that the rear axle weight, when fitted with the standard counterweight, is below 12 tons. Access to the superstructure via steps allows easy servicing/maintenance. Ninety-five percent of the machine is recyclable, according to the company.
Dozer for mining, heavy construction
Komatsu America Corp. says its new D375A-6 crawler dozer is powered by a Komatsu SAA6D170E-5 engine with an operating weight of 157,940 pounds. Features include a net engine output increase to 636 horsepower; a large multi-lingual LCD color multi-monitor; and an easy-to-read “eco gauge.”
Affordable wheel-mounted machines
KPI-JCI says its new RS Series products — jaw and cone crushers, mobile screens, and washing equipment — are designed for portability and simple operation to provide customers with a variety of options at an affordable price without sacrificing toughness and durability.
Track-mounted mobile crusher
Sandvik’s new QJ340 track-mounted mobile jaw crusher, formerly Fintec’s F1107 mobile jaw crusher, is powered by a C-9 engine that meets all known emissions standards. The unit boasts a large feed opening and high crushing speed for high outputs and excellent product size reduction. A reverse crushing action relieves blockages.
Drilling and Blasting
Remote-controlled drill rig
Atlas Copco’s new ROC D3-01 drill rig with built-in, radio-remote-control system is powered by a 116 kW Cummins engine and offers two rock drill options — the 12 kW COP 1240 and the 16 kW COP 1640. The rig can be equipped with R32, T38, and T45 drill steels.
Electronic blast initiation system
Dyno Nobel says its new DigiShot electronic initiation system provides more vibration control, increased crusher throughput, greater highwall stability, and improved operational efficiencies. Blast patterns and timing can be programmed directly or downloaded from a PC-based design program in advance of or on the day of the shot. Write 233 on reader card.
Conveyors and Accessories
Next generation belt cleaner
Flexco says its new MHS Cartridge Cleaner slides out from one side of the conveyor or chute wall, allowing a single worker to inspect, service, or replace it in minutes. The side slide-out design doesn’t require workers to crawl underneath the conveyor or be in tight spaces within a chute.
Railcar unloading system
Grasan’s bulk material unloading system for railroad hopper cars consists of a 140-foot stationary transfer conveyor with under-car feed hopper and 125-foot radial stacking conveyor. Stationary truss and channel frame conveyors are 24 to 60 inches wide, 25 to 500 feet long; radial stacking conveyors are 24 to 48 inches wide, up to 125 feet long.
Skirting extends wear life of belts
Martin Engineering says its improved Apron Seal skirtboard sealing system provides two wear surfaces on a single elastomer sealing strip installed along the bottom of the skirtboard in a belt conveyor loading zone. When the bottom side of the strip is worn, the sealing strip is inverted, providing a second service life.
Superior Industries’ new Slide-Pac three-unit conveyor system has a roll-style slide-off system for safe, speedy unloading of the top two conveyors from the bottom trailer unit. The system is available in lengths of 60, 70, and 80 feet for up to 240 feet of conveyor length.
Crushers and Components
Columbia Steel Casting Co., Inc.’s new anti-slab jaws are based on traditional and high-tooth jaw designs, but with additional raised slab breakers in pitch with conventionally located teeth. Jaws are available in standard manganese steel alloy and in Xtralloy premium manganese.
Small, powerful crusher
Sandvik says its new CJ208 jaw crusher offers a combination of lightweight equipment and heavy-duty crushing applications, and is easy to operate and maintain. The crusher’s bolted feet allow it to be used as a stationary unit with zero-degree inclination or as a mobile unit with five-degree inclination.
Mobile equipment simulation-capable software
BedRock Software, LLC says its new AggFlow with track-mounted (mobile) equipment simulation capability allows users to calculate mass aggregate and water balances flowing through a plant simulation using stationary and mobile equipment. The program helps track and reduce emissions and fuel consumption by refining overall plant efficiency.
Affordable, aftermarket hydraulic system
FLSmidth Excel LLC says it new Sentinel Advanced Hydraulic System is an affordable, aftermarket solution for aggregate producers who want to automate their cone crusher’s clearing capabilities without the purchase of a new crusher. The system’s tramp release cylinders require little or no modification to the existing cone frame during installation.
