Conveyor Technology Rolls Ahead to Keep Pace with Industry Demands/New drives, belts and rolling components maintain capacity but require less energy and maintenance

摘要

For years, in-pit crushing systems and overland conveyors have been a viable option for operators of large surface mines looking for ways to counter rising haulage-related labor, fuel and tire costs. Even shorter, plant-site conveyors have been asked to deliver more-at higher rates, steeper angles and with better resistance to normal wear and tear. With mine operating costs becoming even more intense due to high demand for mineral commodities coupled with a squeeze on available human and equipment resources, the role of conveyors in the mining and milling process has taken on additional importance. Although every mine has site-specific conditions, the object is usually the same: move the most material as quickly as possible at the lowest cost. In this respect, conveyor system suppliers are giving customers what they want, and more. New drive designs and soft start technology allow mines to keep large overland systems operating reliably under heavy loads while improved transfer point, dust control and individual component design contribute to efficiency and reduce environmental problems. Diagnostic systems will allow operators to pinpoint problems and position conveyors accurately. This will help the mines better plan maintenance and significantly lower the chances for catastrophic failure.
