Factors Influencing Screw Conveyor Design | Engineering Guide
Screw conveyors must be fabricated from abrasion resistant alloys. Typical materials of construction are AR235, AR400, AR500, TriBraze or chromium carbide overlay. These materials are harder and tougher than A36 carbon steel for resisting abrasion. The carrying face of the screw may be hardsurfaced with a weld-on hardsurfacing material.

nearly 1.9mm. Now, they modified the diameter of the screw conveyor for a Shaftless type Screw Conveyor, and performed the analysis; surprisingly the stress was nearly 1/2 i.e., 70MPa and the deformation was comparatively negligible i.e., 0.2mm. Also, the power consumption as found for the shaftless conveyor was 16% less [4].
