High reduction ratio Metso's new HP3 cone crusher, the third model in an all-new range of high-performance cone crushers, is now available in North America. The company says it provides the highest reduction ratios of any cone crusher in its class, producing finer products using fewer crushing stages and saving customers energy and operating costs. Its highcavity density is said to improve inter-particle crushing action for end products with consistent gradation and superior shape. Major enhancements include dual-acting hydraulic tramp release cylinders that enable the crusher to pass tramp iron without stalling or damaging internal components. If the crusher does stop under load, the dualacting cylinders provide a large clearing stroke to quickly and safely clear the crushing cavity. An advanced fastening system for the mantle and bowl liner eliminates the need for backing material, making liner changes fast and easy. The crusher features an IC700 automation system for optimum operating parameters. Metso Minerals Industries, Inc. | www.metso.com Powerful dust suppression Dust Control Technology says its new DustBoss DB-100 dust-suppression unit is engineered for use in large quarries. With a range of more than 328 feet, the machine is able to reach stockpiles 200 to 300 feet high. The atomized misting unit stands nearly 10 feet tall and can cover an area of 280,000 square feet from a single location. The machine is fed by a manifold of 30 brass nozzles that are specifically sized and positioned. It features simple, user-defined, 359-degree oscillation with an adjustable elevation from -7 to 45 degrees and can be outfitted with a dosing pump to meter in surfactants or tackifiers to enhance the binding of dust particles. Despite its large size, the unit is said to require minimal maintenance — lubrication of fan motor bearings is recommended every 10,000 hours, while the oscillating motor is lubricated for life. Dust Control Technology | www.dustboss.com Rapid deployment system IRock says its new RDS-20 primary crushing plant is a highly portable, easy-to-operate mobile unit that combines a closed-circuit design, a highperformance four-bar impactor, and heavy-duty components. The rapid deployment system (RDS) features a 5-foot by 16-foot, double-deck screen and can crush, screen, and separate up to three different sizes of materials — two sized and one crusher run — at a rate of up to 500 tons per hour. The initial vibrating feed opening is 52 inches by 17 feet, while the crusher feed opening is 56 inches by 32 inches. The plant's closed-circuit design allows both decks of oversized material to return to the feeder for another pass through the crusher after the initial round of screening. The crusher is powered by a 440-horsepower Caterpillar C-13 ACERT Tier 3 engine, but can be equipped with a Tier 4 engine. IRock | www.irockcrushers.com Increased tractive effort Komatsu's new WA470-7 wheel loader is powered by a Komatsu SAA6D125E-6 Tier 4-interim engine that boasts 272 net horsepower. The machine weighs 52,007 pounds and features a newly designed large-capacity torque converter with Lock-Up, which the company says provides improved acceleration, faster hill-climb ability, a higher top speed, and lower fuel consumption. The Lock-Up function activates in second, third, and fourth gears, giving the machine a maximum ground speed of 23.8 miles per hour. The loader has greater productivity in V-cycle applications because of the increased tractive effort. The faster hill-climbing ability allows it to up-shift gears faster, achieve higher gear ranges, and maintain higher ground speeds when working in load-and-carry applications. The cab's front glass has been lowered and the dashboard redesigned to improve visibility.
