Screw Conveyor Capacity Engineering Guide

A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm

STANDARD SCREW CONVEYOR DIMENSIONS

CAPACITY of a screw conveyor is determined volumetrically. If a given weight of product is to be conveyed in a specified time, the loose bulk density of the product must be known to determine the actual volume to be conveyed. Most products have a lower bulk density when agitated or aerated during conveying than when at rest. The lowest bulk density must be used to calculate the volume to be ...

Screw Conveyor Basics: Screw Conveyor Fill Rate - JMS

A best-case scenario for a screw conveyor would be a dry granular product fed at a very measurable and consistent volumetric flow rate. In that case, theoretically a short horizontal shafted or shaftless screw conveyor could be designed at 100% trough fill rate. Most conveyor manufacturers however, recommend limiting trough fill rate to 45% maximum even at ideal cases (non-submerged apps) for ...
