The single-idler Quarry King conveyor belt scale was designed for outdoor conveyor weighing of dusty fines and stonelike aggregate materials, where rugged construction and spillproof and jamproof suspension are the most valuable attributes. Complementing the unit’s proven rocking flexure fulcrums is a completely new pipestem single-idler suspension system, which incorporates built-in storage for its calibration weight. Test chains are not required. This combination of elements provides important advantages for operations in which on-going dust buildup and spilled aggregates are known to foul conventional suspension designs. Applications include 18–48-in.-wide troughed belt conveyors that operate at speeds of up to 600 fpm and inclines up to 18°.
