Screw Conveyoran overview ScienceDirect Topics

An auger conveyor (or screw conveyor) consists of a helicoid screw rotating within an enclosed tube or open U-tube (Fig. 3.7) s invention is credited to Archimedes (287-212 BC) who used it to pump water from the holds of ships (CEMA 2003).With only one moving part in contact with grain low-cost augers are simple and find extensive use especially in intermittent use conveying systems.

Design and fabrication of a screw conveyor

The conveyor was fabricated from local materials considering the physical properties of the selected grains the techno-economic properties of the machine. The conveyor is powered by an electric motor through a V belt connection. Tests were run on the conveyor using common granular materials like maize sorghum and gari at 13 moisture content.
