Screw Feeders | Bulk Material Transport
Screw Feeders utilize a screw rotating in a housing to transport the material and are flood loaded in the inlet area. The bulk material moves forward with each revolution of the screw and is metered through a shroud for accuracy. Metering capacities up to 10,000 cubic feet per hour can easily be handled with Kase Screw Feeders.

Screw Feeder
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. This, of course, will provide a perfectly valid alternative data point.
