As one of leaders of conveying run of mine materials industry, SBM always seeks innovation & excellence.
Primary crushers or feeder-breakers are utilized to process material in the pit. HAC systems elevate properly sized material from the pit to overland conveyors for processing. A HAC system can convey material at very steep angles, high lifts and capacities over 8,000 MTPH, saving you up to 50% in material handling costs.

Conveyors are more flexible than you think. One of the main benefits of utilizing trucks in mining operations is their flexibility. Especially at mines that may not have a long "expected life of the mine," or LOM, left. In these cases, conveyors may still meet your needs, though they may not entirely replace trucks in your operation.
