The Quarry King Single-Idler Belt Scale is designed for outdoor conveyor weighing of dusty fines and stone-like aggregate materials. The scale combines “Rocking Flexure” fulcrums with a new pipe-stem, single-idler suspension system, incorporating built-in storage means for its calibration weight, ideal for areas where dust buildup fouls suspension designs. Troughed belt conveyors of 14–48-in. belt widths (Series 1RF-3A for 14-, 18-, 24- and 30-in.; Series 1RF-4A for 36-, 42- and 48-in. belt widths) are available, operating at speeds up to 600 ft/min and inclines up to 18 degrees. — Thayer Scale, Pembroke, Mass.
