Special Conveyor Screw Designs: The double flight design is designed with two rows of flighting that are the same hand (right or left) wrapped around the screw conveyor pipe. This design has an outcome of more evenly dispersed discharge from the system which minimizes surges, this can be particularly desirable when feeding into a scale hopper.
The design promotes agitation by moving material from the bottom of the trough to the top, unlike a cut flight design. Material capacity is reduced with this design as well, this time by a factor of 3.0-3.5x. As an example, a regular flight conveyor carrying 9.0 tons/hour would carry 2.6-3.0 tons/hour as a cut and fold conveyor.

David Mills, in Pneumatic Conveying Design Guide (Third Edition), 2016. Feeder Considerations. Screw feeders and rotary valves are positive-displacement devices and so the feed rate is unlikely to change. In this case an improvement in performance will be recognized in terms of a reduction in conveying-line pressure drop.

Screws. The performance-proven materials of construction of every National Bulk Equipment flexible conveyor screw; together with its process-specific flight design, pitch, and finished machining, ensure sustained conveying accuracy, at designed capacities, of even the most demanding materials and bulk densities.
Diverters are used to move products off the main conveyor by pulling or pushing. Drag conveyors (drag chain conveyors) pull or drag material through a tube or U-shaped trough. Screw conveyors consist of a helical flight fastened around a rigid pipe or solid shaft, mounted within a tubular or U-shaped trough.
Screw Conveyors Design Data . No machinery design is complete without considering its usage. A conveyor that will be used intermittently for two hours a day does not have to be built as heavily as one that will operate twenty-four hours per day. Likewise, shock loads will affect the consideration given on gauge of steel ...
