Complete Screw Conveyor Designer (PREMIUM)

Primary fabrication tool for Jhandeana: computes the outer & inner unwrapped arc lengths, number of turns and a first-pass flat blank area/length. Use these outputs to create cutting nests, estimate plate usage, and prepare CAD patterns. Final patterns should be verified in CAD with springback allowances.

Units

Outer Diameter (mm)

Inner Diameter (hub) (mm)

Pitch (mm)

Axial Flight Length (mm)

Flight Thickness (plate) (mm)

Terms Used in This Calculator

Turns: Axial length divided by pitch — how many revolutions the flight contains.
Outer/Inner Arc: Length of the curved edges when unwrapped — used to size flat blanks.
