Screw Conveyor - an overview | ScienceDirect Topics
Screw Conveyors A screw conveyor consists of a helicoid screw rotating in an enclosing tube or open “U-tube” Its invention is credited to Archimedes (287–212 BC), who used it to remove water from the holds of ships (CEMA, 1980) With only one moving component in contact with the corn, screw conveyors are used extensively in low-cost .
