| Radial Stacker Conveyor Design Information |
The size radial stacker needed is dependent upon the stockpile volume that needs to be conveyed. Below please find a chart and formulas that will help you to determine the best conveyor size for your needs.

Calculated volumes are in cubic yards.
Tons are base on 100 Ibs. 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 Ø are known:
Where height of pile (H) and angle of repose (Ø) are known:
V1 = H3 (.039)
(tan 02)
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 Ø is equal to 31° V2 = H2R
1160
b. For other angles of repose V2 = H2R
(1547) (tan Ø)
3. Degrees of arc of stockpile with known arc lengths = Ø. Where diameter of stockpile (D) and
arc length (A) are known: e = (114.6)A
D
