Despite their apparent simplicity, their mode of operation is far from simple. For this reason, it is important that conveyor designers, manufacturers and users have some understanding of the basic mechanics governing their performance. This discussion of screw conveyor fundamentals draws upon background research that is presented in Refs. 1–7.

With the growing increase in the bulk handling of grain, the grain-auger type elevator is now being widely used. While some theoretical analyses of the grain auger have been made and performance data for particular size augers have been obtained, little information is available for general design purposes. This work, which is based on an experimental …
The design of screw feeders requires detailed consideration of the geometry at the interface of the screw and the feeder. This paper focuses on the determination of the required screw geometry to achieve specified draw-down performance objectives. A theory is presented which takes into account the screw geometry and variable volumetric …
