Terex Washing Systems plans to roll out the AggreSand system during the second quarter of 2013. The AggreSand design incorporates Terex washing systems in a modular design that is pre-wired and pre-plumbed to allow for quick and easy set-up, as well as ease of maintenance. A 12-cubic-meter hopper is available with an automatic tipping grid and a 12-foot, two-deck vibrating grid complete with variable speed belt feeder, all controlled from the main operator interface and radio control unit. A wide feed conveyor sports a direct drive electric motor and gearbox arrangement and will work at a 19-degree angle when feeding the system. The three-deck, two-bearing rinsing screen has riveted construction to reduce stress associated with welds. Each deck has eight individually controlled spray bars, which are isolated from vibration. A split sump tank receives rinsed fines from the bottom deck of the screen while two centrifugal slurry pumps move material from the sump tank into two hydrocyclones. Underflow from the hydrocyclones goes to a dewatering screen fitted with two counter rotating vibratory motors. The unit also has the option of three aggregate and two sand conveyors, which are powered by direct drive electric motors and gearbox arrangements.

Caterpillar has added three new models to the E Series Hammer line — H140Es, H160Es, and H180Es—for use on medium and large excavators. The units have a rugged design for extended durability and solid reliability and boast features such as an automatic shut-off, silencing, and vibration buffering to make them easier on the operator. Common hand tools may be used for field service. The hammers match up with Cat excavators ranging from the 324E to the 374D L; mounting brackets are available for quick couplers. The energy class ranges from 6,000 foot-pounds to 12,000 foot-pounds. A symmetrical new housing design allows 180 degrees of rotation to compensate for wear.

Philippi-Hagenbuch, Inc. introduced a new design for its Aggregate HiVol Body. The new body, developed for use in quarry environments, fits all brands of off-highway, rigid-frame haul trucks. Designed to match the life of the truck, the new body is said to decrease material carryback of stick material. Engineers gather information on height and width restrictions, as well as loading tools and hopper/loadout, to create a body tailored for maximum productivity and minimum maintenance according to site-specific needs. The body’s design also incorporates the tailgate, allowing for maximum payload.

Elrus says its new compact 6- by 12-foot three-deck screen plant was designed with an emphasis on increasing plant efficiency, reducing size and weight, and reducing the overall cost of ownership. It incorporates two screening sections on each deck, offering the benefits of both horizontal and inclined screening. The primary high-angle panel at the feed end results in rapid fines removal, while the secondary lower-angle panel results in accurate sizing and stratification.

The McCloskey V80 vertical shaft impactor is now available around the world. The company says it is designed to be one of the most efficient vertical shaft impactors on the market for producing high-specification sealing aggregates, with a high proportion of fines required for main roads/road base, or manufactured sand. The plant features a Cemco crusher, a heavy-duty feeder with hardox steel hopper, a 350-horsepower Cat C9 engine, and four possible crusher combinations for higher efficiency and less wear.

Flexco says its new, easy-to-install PT Smart Belt Trainer is made of durable materials and works with both mechanical and vulcanized belts. The item features pivot and tilt technology that is said to correct even the most stubborn tracking problems on medium-tension belts. A fully enclosed stainless-steel pivot bearing located downstream from the roller creates an almost immediate tracking result. The bearing requires no lubrication and is guaranteed not to seize.

Screen Machine says its revolutionary, patent-pending, track-mounted CST cone crusher features a 50-inch quarry-duty cone crusher that offers the highest weight-to-power ratio of any tracked cone plant in the industry. It is uniquely designed with a vibratory shaker screen located between the feeder and crushing chamber.

ASGCO says its new external skirtboard/wear liners, which mount on the outside of skirtboards protect and improve the conveyor skirtboards and sealing system. An adjustable bolt-on system allows for ease of inspection, adjustment, and replacement without having to enter the internal area of the load zone. The liners maintain the correct distance between the skirtboard and conveyor belt to keep dust and fugitive material from escaping.

W.S. Tyler now has a 4-foot-wide version of its F-Class Vibrating Screen, allowing its double eccentric screening system to be used in operations with smaller footprint and capacity needs. The F-Class’ consistent G-Force is said to reduce blinding and pegging, even with sticky material. The screen can process 300 tons per hour, with material ranging from 3 inches to 20 mesh. It can run with up to three screen decks and with inclines ranging from 15 to 25 degrees. A huck-bolted design provides extra strength and rigidity. The 4-foot unit joins a line-up with 6-, 8-, and 10-foot-wide platforms.

The new G900B-Series generation of motor graders from Volvo are said to feature the highest blade down pressure in each weight class. The range consists of the 34,520-pound G930B, the 35,843-pound G940B, the 37,827-pound G946B, and the 38,709-pound G960B. They each feature new, larger displacement engines with increased power and torque compared to the models they replace. The engines use exhaust gas recirculation (EGR) technology and feature three power curves with the 8×4 transmission and eight curves with the 11×6 transmission to vary the power to match the level of traction available as well as to optimize the hydraulics and drive train. The units have eight forward and four reverse gears as standard equipment, with the option of 11 forward and six reverse gears. ‘Shuttle shift’ transmission allows easy shifting between forward and reverse gears without the need to stop or use the inching pedal. Volvo’s exclusive circle turn system features two pinions driven by twin direct acting hydraulic cylinders, which provide instant, high output torque.
