Full definition
The transverse dimension of a conveyor belt, a primary design parameter that, combined with belt speed and trough angle, determines the volumetric conveying capacity. CEMA standard widths (inches): 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, 96. Metric standard widths (mm): 400, 500, 650, 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200. Selection per CEMA/DIN 22101: width must be at least 2-3x the maximum lump size for grizzly-screened material, or 3.3-4.5x for unscreened run-of-mine. Wider belts allow lower speeds (reducing wear and dust) for the same tonnage. Edge clearance from skirting: minimum 50-75 mm per side. Belt width also determines idler station width, structure gauge, and transfer chute dimensions. Most common in Latin American mining: 1000-1600 mm.
