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.
