Basic Screw Feeder Design A screw is designed to move bulk materials from one flight to the next during every revolution. Therefore, if the screw is 100 percent loaded and the capacity is the same for each flight, new material can only be introduced to the first flight under the storage device, opposite the discharge.

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.
