Screw Conveyor Capacity | Engineering Guide
A 16inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1rpm. 1,873/ = 60rpm. 60rpm is the correct speed for a 16inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing .

All About Screw Conveyors (Auger Conveyors)
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). However, they function almost identically to screws, where a drive motor turns the screw (also known as the auger), moving product up one pitch every revolution. The auger is ...

Designing Inclined Screw Conveyors for Industrial ...
· Loss in efficiency can be overcome by increasing the speed of the screw conveyor, increasing the diameter of the screw conveyor or reducing the pitch of the screw. • Incline Between 10 and 20 Degrees – Loss in conveying efficiency is typically between 10 and 40 percent on inclines up to 20 degrees. A screw conveyor with Utrough and 2/3pitch screw is sufficient for most appliions. .
