An auger conveyor or screw conveyor consists of a helicoid screw rotating within an enclosed tube or open Utube Fig 37Its invention is credited to Archimedes 287212 BC who used it to pump water from the holds of ships CEMA 2003With only one moving part in contact with grain lowcost augers are simple and find extensive use especially in intermittent use conveying systems

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 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 semisolid materials including food waste wood chips

The screw pump is often referred to as the ‘Archimedes pump’ The screw conveyor has slightly different design properties but the overall concept remains the same Operating Principle of a Screw Conveyor Materials liquid or solid state are loaded into the conveyor and pushed along by a helical screw blade ‘flighting’ mounted onto
