At its simplest, bulk materials enter the screw conveyor, riding in the bottom of the housing as the screw shears through the substance, moving the product forward with each revolution and pushing it closer to its destination. A typical screw conveyor consists of flights mounted on a pipe in an enclosed housing, supported by bearings (Figure 1).

A screw conveyor with tubular housing and reduced pitch screw (1/2 or 2/3) is recommended for most applications. Loss in efficiency can also be overcome by increasing the speed or the diameter of the screw conveyor. Additional horsepower is required to overcome gravity and bulk material fall back.

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