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.

Sizing a Screw Conveyor
The first step in sizing a screw conveyor is to determine the diameter. The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are ...
