A screw conveyor, also called an auger is a mechanical conveying device for powder bulk solids. At the heart of the screw conveyor is the screw. See here for information on screws The screw is rotated by the drive and pushes the conveyed material forward 1 pitch with every revolution. The first recorded use of a screw conveyor was by Archimedes around 250 B.C.

Power Required for Different Materials The graph in Figure 2 shows the calculated horsepower draw for three different size feeders using five different powders. The horsepower is graphed versus the size auger. The auger is sized based on the rate required. The power draw is a result of the size of the auger and the friction factor for the material.
Rotary valves, screw feeders, belt conveyors, grinders, or even other screw conveyors typically are connected to the inlet of a screw conveyor. Screw feeders are similar to screw conveyors except that screw feeders are always flood loaded or 100-percent full in the inlet area.
A screw conveyor also known as an auger conveyor is, unsurprisingly, the shape of a typical screw, albeit with some caveats. Firstly, the threads are exaggerated and the center may or may not be present see Figure 1. ... where coupling bolts transmit the motor torque to power the conveyor. A tube or U shaped trough around the auger acts as ...
Therefore, the materials delivery inside the conveyor is like a kind of slip movement. To have the screw shaft under better pulled state, normally have the motor and discharging port at same side of the screw conveyor. And have the outlet at the other end of screw. The screw blade push the materials to realize materials-delivery.
A 10-inch conveyor 35 feet long with a capacity of 10 tons per hour at 45 RPM has been selected. From the Materials Table, a Horsepower Factor of 0.8 is found for the material to be conveyed. The table also indicates Series 4 hanger bearings and shafts.

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.
