Screw Feeder - an overview | ScienceDirect Topics

David Mills, in Pneumatic Conveying Design Guide (Third Edition), 2016. Feeder Considerations. Screw feeders and rotary valves are positive-displacement devices and so the feed rate is unlikely to change. In this case an improvement in performance will be recognized in terms of a reduction in conveying-line pressure drop.
