Inclined Screw Conveyor Calculation | Mechanical ...

Actually, since an inclined screw conveyor is used to move material up vertically as well as horizontally, the amount of energy (and therefore over time, horsepower) needed to move a given amount of material would increase based on the overall height which needs to be traversed, in addition to the energy needed to move the material horizontally along the conveyor.

Conveyor Capacity - Engineering ToolBox

Conveyor Capacity. Conveyor capacity is determined by the belt speed, width and the angle of the belt - and can be expressed as. Q = ρ A v (1) where. Q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m3, lb/ft3) A = cross-sectional area of the bulk solid on the belt (m2, ft2) v = conveyor belt velocity (m/s, ft/s)
