Shaftless screw conveyor capacity is calculated using the spiral diameter, spiral pitch, trough loading percentage, degree of incline (if any) and spiral rotational speed. The required speed is then calculated by dividing the required material flow rate by the capacity per revolution. "D" and "d" are the outer and inner diameters of the ...

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), …
