Some Aspects of the Characteristics of Vertical Screw Conveyors for Granular Material* F.J C. RADEMACHER Afdeling der Werktuigbouwkunde ucn de Technische Hogeschool Twente, Enschede (The Netherlands) (Received July 18, 1973) Summary A theory has been developed, based on a physical model, to describe the behaviour of non-cohesive granular material inside a ver- tical screw conveyor…
Screw Conveyor Capacity | Engineering Guide
The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333 cubic feet per hour.

Shaftless Screw Conveyor Calculations | …
Shaftless screw conveyor capacity is calculated using the spiral diameter, spiral pitch, trough loading percentage, degree of incline (if any) and spiral rotational speed. The required speed is then calculated by dividing the required material flow rate by the capacity per revolution. “D” and “d” are the outer and inner diameters of the spiral. “I” and “R” are factors related ...
