Belt Capacity Chart

The following conveyor belt capacity charts show tons per hour (TPH) based on material weighting 100 lbs. per cubic foot, 20° material surcharge angle with three equal length rools on troughing idlers.

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

Calculated volumes are in cubic yards.

Tons are based on 100 lbs. per. Cu. Ft. material, conveyor incline 18 stockpile angle of repose 37.

Live Storage at center of pile is theoretically 25% of the total volume

1. Volume of conical pile = V₁

Where radius of pile (r) and height of

pile (h) are known: V₁ = r²H (.039)

Where height of pile (H) and slant length of side

of pile (s) are known: V₁ = H (S²-H²) (.039)

Where slant length of side of pile (s) and

angle of repose ∅ are known:

V₁₁ = S³ (cos ∅)² √1 - (cos ∅)² (.039)

Where height of pile (H) and angle

of repose (∅) are known:

V₁ = H3(.039)/(tan ∅²)

2. Volume of a 1° arc segment of stockpile = V₂

a. Where height of pile (H), distance between center line

of pile and center line of conveyor pivot (R) are

known, and angle of repose ∅ is equal to 37° V₂ = H²R/1160

b. For other angles of repose V₂ = H²R/(1547) (tan ∅)

3. Degrees of arc of stockpile with known arc lengths = ⊖.

Where diameter of stockpile (D) and arc length (A) are known:

⊖ = (114.6)A/D
