Screw Feeder and Screw Conveyor Design Calculation/h2>

This page allows you to calculate some of the design parameters for a screw feeder or screw conveyor. This is a responsive form in that you don't have to press a button to perform the calculation, you just change an input.

Changing the dimensions of the feeder or conveyor for a given volumetric throughput (based on mass throughput and density) will change the machine speed. Changing the mass throughput and/or density with fixed dimensions changes the machine speed. Changing the machine speed changes the throughput.
