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.
