Tests Prove Off-road Engine Runs at 315 kW

Volvo Penta announced higher power output for its latest 11-liter diesel engine, now rated at up to 315 kW, from the initial 285 kW. The higher power output has been verified through extensive testing. The engine features a matching exhaust after treatment system that complies with forthcoming European Union Stage V emissions regulations. It is equipped with a fixed-geometry turbo. The air inlet throttle, together with the uncooled exhaust gas recirculation, and the electrical exhaust pressure governor deliver highly effective heat management of the engine, the company reported. This enables the system to function without the need to inject fuel into the exhaust stream.

Cone Feeder Reduces Needed Equipment

Deister Machine Co. Inc. introduced the new EMCO 360 Crusher Optimizer Feeder, a two-mass electromechanical vibrating feeder. Featuring a 360° discharge opening, the unit distributes a homogeneous feed to cone crushers, keeping cones choke-fed for optimum efficiency, greater manganese wear life, improved production rates, and the consistent yield of a more cubicle product. The feeder eliminates the need for two pieces of equipment, the traditional flat pan feeder and a rotating feed distributor, the company said. Its design incorporates the action of the rotating feed distributor to evenly distribute the material into the cone to minimize uneven rock buildup within the crusher. It is available in a range of sizes and capacities.

System for Customizing Truck Bodies

Philippi-Hagenbuch announced deployment of Predictive Load, a system that customizes HiVol and Load Profiled truck bodies per customer specifications. The system considers the materials and haul cycles to provide accurate analysis of the loads, the company reported. In addition, it considers the loading height and the type of loading equipment the mine is using, since each interacts with a truck body differently. Matching the truck body to the loading height and equipment minimizes damage to the loading equipment as well as the truck body’s sides. It also ensures optimal load centering, which improves the life of the truck chassis and tires as well as reduces damaging impacts from loads. The system also ensures the truck body floor has the appropriate configuration and is angled correctly for sufficient dumping and the greatest practical chute dump clearance.
