The screw conveyor is one of the most popular choices for processing and manufacturing, meaning there are many, many iterations of this design. This section will go through a general classification of screw conveyors available and what sets them apart from other unique designs.
The horizontal screw conveyor is the most distributed version of the screw conveyor, thanks to its simple and easy to use design. They can convey materials at 15-45% trough loading, defined as the maximum trough capacity divided by the specified trough load for a given material. A more viscous, sluggish material will require a lower trough load, while a lighter free-flowing bulk can be fed at a higher load.
