Screw Conveyor - an 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).Its 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.
