Belt Capacity Chart
The Following conveyor belt capacity charts show tons per hour (TPH) 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.)
