Calculation of the nominal flow can be done once the screw geometry, its rotation speed and the filling coefficient are known. The flow rate of a screw conveyor or feeder depends on a number of interlinked factors: - geometry of the screw - rotation speed - inclination - geometry of the feed hopper and tube - flowability of the material.
