* kN per mtr : Full Thickness Tensile Strength # values subject to manufacturing tolerance.
Carcass thickness of rubberized fabric plies also manufactured to desired total belt thickness, thus, weights given are as per above thickness, else proportionately increase-decrease weight roughly as per total inter-ply thickness.
Approximate cover Weight of M24, N17 and HR grades rubber per 1 mm thick = 1.1 kg/M2

Conveyor Belt Capacity Ton Per Hour in relation to Speed

Conveyor belts capacity in tons per hour (TPH) is based on material weighing 100 lbs. per cubic foot, 20° material surcharge angle with three equal length rolls on troughing idlers.

CAPACITY (TPH) = .03 x Belt Speed (FPM) x material weight (lb. per cu. ft.) x load cross section (sq. ft.)
