The first step in sizing a screw conveyor is to determine the diameter, which is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. Once the diameter and RPM of the screw conveyor are known, the motor horsepower (HP) must be determined. The basic HP calculation set for screw ...

Screw Conveyor Sizing Flow Rate and Screw Size. Since the purpose of a screw conveyor is to move product from point A to point B, you'll want to determine how fast you want the product to move (this is called the flow rate or capacity). Of course, a screw conveyor can only hold so much material at one time, but the bigger the screw inside the conveyor and the lighter the material, …
