Electromechanical vibrating feeder
Deister Machine Co., Inc. will launch the newest addition to its lineup of screening, scalping, and feeding equipment — the New Deister Two-Mass Electromechanical Vibrating Feeder — at AGG1 in Baltimore. The feeder is designed to allow greater control over high-capacity feed rates and productivity, while lowering costs per ton in aggregate operations. Units in the Deister EMF Series incorporate a high-profile infeed lip and a heavy-duty formed deck with replaceable liners. A simplified drive is designed with an easy-access exciter frame, which houses the single vibrator motor. Deister says the design results in higher bearing life and eliminates the need to replace belts.

Tandem vibrating screen
W.S. Tyler’s Tandem F-Class Vibrating Screen provides an alternative to machines larger than 10 feet by 24 feet by placing two 10-foot by12-foot F-Class machines in tandem and operating on a 15- to 25-degree incline. The manufacturer says this offers operational benefits such as cleaner operation, less maintenance, and longer life for the structure that houses them. In this configuration, each unit feeds the other. Tandem configuration can be used for both two- and three-deck units, and a 3-inch drop between screens promotes additional material tumbling to facilitate passage of any remaining fines through the screen. Discharge lips and rubber skirting minimize spillage during the transition.

Mobile cone crusher
Kleemann says its Mobicone MCO 9i EVO/MCO 9i S EVO mobile cone crushers offers aggregate producers high-productivity secondary or tertiary crushing in fuel-efficient, Tier 4 Final compliant machines. The S-version provides a discharge conveyor-mounted final classifying screen with oversized aggregate return conveyor to allow a closed material cycle and production of final particle sizes without a standalone screen. Optionally, oversize material can be discharged via the swivel-mounted return conveyor at the side. The unit’s diesel-electrical drive provides low fuel consumption. Its power plant generates 332 horsepower at 1,500 rpm, and the unit can crush up to 287 tons per hour with a feed size of up to 8 1/4 inches. The standard hopper feed opening is approximately 8 feet, 3 inches wide by 11 feet, 2 inches long.

More powerful dozing
John Deere’s new crawler dozers, the 750K and 850K, not only meet Tier 4 Final emissions standards, but also include features such as EcoMode and an updated Electro-Hydraulic control system. The new control system has features such as blade shake for power-angle-tilt configurations, improved blade response, and rear auxiliary configurable settings to enhance operator productivity. The units feature a PowerTech 6.8-liter Tier 4 final diesel engine with 165 horsepower and 205 horsepower, respectively. The 850K is the first John Deere unit to feature EcoMode, which optimizes fuel economy while maintaining ground speed by automatically adjusting engine speed and transmission settings based on load. The manufacturer estimates the feature can save customers up to 20 percent in fuel costs.

Long-life rotors
Metso’s new Orange Series Rotor components for vertical shaft impact crushers are said to substantially increase uptime through longer parts life and faster service. The manufacturer says the components were reconfigured with a built-in possibility for easy interchange, while the change out of primary components through the service door was also improved. It estimates that the total number of wear parts has been reduced by 30 percent, and the total number of components has been reduced by 25 percent. At the same time, Metso says tip life was increased by 30 to 50 percent.

Blade improves dozing power
Komatsu America Corp.’s D155AZ-8 crawler dozer has an operating weight of 89,300 pounds. Rated at 354 net horsepower, it is powered by a Komatsu SAA6D140E-7 engine, which is Tier 4 Final certified. Equipped with the latest Komatrax technology, data on fuel levels, DEF levels, operating hours, location, cautions, and maintenance alerts are relayed on the web application. The dozer is also equipped with a 12.3-cubic-yard Sigmadozer blade, which is said to improve dozer performance and increase productivity by up to 15 percent over a conventional Semi-U blade. Its unique shape increases soil-holding capacity, and digging resistance is reduced for smoother flow of material so larger amounts of soil can be dozed with less power.
