Types of Screw Conveyors | Engineering Guide
The inlet of a screw conveyor is always control fed by another device such as: Screw Conveyor. Screw Feeder. Belt Conveyor. Rotary Airlock. Volumetric or Gravimetric Feeder. The recommended location for the drive unit is on the discharge end of a screw conveyor which pulls the bulk material to the drive end.
CEMA Screw Conveyor Engineering Standard 351-2007
Screw feeders are volumetric metering devices. A fixed volume of product is discharged with each revolution of the screw. The volumetric capacity of the screw feeder is based on the volume available in the last pitch before the shroud and the speed of the unit. All calculations are based on the capacity given in cubic feet per hour.
