For maximum efficiency, feeder screw speeds should be slower than standard screw conveyor speeds and allowances must be made for slippage of the material in the screw. Factors Affecting the Design Of A Screw Feeder …


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.

For uniform draw with a fully active hopper outlet, the capacity of the feeder must progressively increase in the direction of feed. In the case of a screw feeder, for example, this is achieved by using combinations of variable pitch, screw and core or shaft diameter. In the case of belt and apron feeders, a tapered opening is

Screw conveyor design calculation - an Engineering Guide
