DESIGN AND SIZING OF SCREW FEEDERS
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.

Top 10 Considerations for Pneumatic Conveying Systems Design
Conveyor design can change based on the type of process equipment being fed such as loss in weight feeders, volumetric feeders, mixers, extruders, packaging and other equipment. For example, a loss in weight (LIW) feeders require quick refill. Knowing that the equipment is loading into a LIW feeder influences the design of the system.

Multiple Screw Feeders, Live Bottom Feeders
Multiple Screw Feeders. Screw feeders are generally under bins, hoppers or silos. When materials flow through the feeder, characteristics from the bins, hoppers or silos are considered. The length width of the bin, hopper or silos discharge are usually called out to insure proper flow to the screw feeder inlet.
