What Are Auger Screw Conveyors

Auger screw conveyors are mechanical devices used for the transportation of bulk materials from one point to another. They consist of a helical screw element, known as a flighting, that rotates within a tube or trough, moving the material along the conveyor’s length. This simple yet effective mechanism is the backbone of many industries, facilitating the smooth and continuous flow of materials.

The primary function of auger screw conveyors is to move materials efficiently and reliably over short to medium distances. They are particularly adept at handling a wide range of materials, including powders, grains, flakes, pellets, and even liquids. Their versatility makes them an indispensable tool in numerous applications, from agriculture and food processing to construction and manufacturing.

The basic operating principle of auger screw conveyors harks back to the ancient design of Archimedes’ screw. Archimedes’ screw was originally developed for lifting water and consisted of a helical surface surrounding a central cylindrical shaft. As the shaft turns, the bottom end of the screw draws in the material and pushes it up the shaft as the screw rotates. The material then exits at the top of the screw.

Similarly, in modern auger screw conveyors, as the screw (flighting) rotates within a fixed tube or trough, the material on the bottom side of the trough is carried up from the feed end to the discharge end. The rotating helical blade acts as a continuous ramp, moving materials along the length of the conveyor and out the discharge end. This process is continuous, with new material being drawn into the conveyor as the old material is discharged.

The efficiency of an auger conveyor depends on the design of the flighting, the speed of rotation, and the characteristics of the material being moved. The pitch and diameter of the screw, the type of material, and the operating environment all play crucial roles in determining the conveyor’s effectiveness and efficiency.
