And to find the cylindrical screw flights, divide the products of developed inside diameter and overall radius by the reduced value of developed outside diameter and inside diameter. Formula: D = (A - B) / 2

You have D (outside flight diameter), d (inside flight diameter), P (pitch of flight). So consider that b is the result of (D-d)/2. Now developed the outside diameter,

2021-6-27  Compressing Flight. Compressing flight centres provide a continuous decrease in swept volume of the screw. This compresses and compacts the material as it is conveyed. The flights are typically canted forward to counter the forces of the compacting process. These are used in compacting, dewatering and decanting situations.

2008-1-9  Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases 2. The efficiency of moving the material forward decreases.
