Conveying Capacity
Determining conveyor capacities
Sponsored Links
Conveying capacity is determined by speed, belt width and troughing angle and can be expressed as
Q = ρ A v (1)
where
Q = conveyor capacity (kg/s, lb/s)
ρ = density (kg/m3, lb/ft3)
A = cross-sectional area of the bulk solid on the belt (m2, ft2)
v = belt velocity (m/s, ft/s)
The cross-sectional area of the bulk solid on the belt can be expressed as
A = U b2 (2)
where
U = non-dimensional cross-sectional area shape factor
b = contact perimeter between bulk material and belt (m, ft)
Non-dimensional cross-sectional area shape factors for various troughing belts are available from manufacturers' handbooks.
