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.

Metering Screw Feeder - Wrights Dowson Group

The influence of screw feeders on bin flow patterns ...

1996-7-1 · Screw feeders are often used in bulk solid handling systems to control the feed from mass-flow bins with wedge or transition shaped hoppers. This requires good geometric design of the outlet-feeder combination in order for the bulk solids to be entrained over the full length of the outlet. Otherwise, unnecessary problems are likely to occur.
