Screw conveyor Wikipedia
A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including stone waste, stone chips, aggregates, cereal grains, animal feed, boiler ash, meat and stone meal, municipal solid waste, and many others. The first t
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.
Screw Conveyor Capacity Engineering Guide
A larger screw conveyor diameter will be required for lower screw conveyor speeds. Maximum lump size must also be considered when designing a screw conveyor. Please refer to the Bulk Material Lump Size section for further information. The Capacity Table is only intended for designing control fed screw conveyors.
Screw Conveyor Components Motion Industries
Screw conveyors transport liquid or bulk materials. They have a helical screw blade, or auger, that rotates to move granular materials along the conveyor line horizontally or at a slight incline. The auger sits in a tubular housing to keep materials in the conveyor. Screw conveyor parts and accessories include discharge spouts, screw clamps

Types of Screw Conveyors Engineering Guide
Inclined screw conveyors typically operate from slightly above the horizontal position to 45-degrees from the horizontal position. Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors.
