How to increase capacity of an inclined screw conveyor

2020-12-14 · The capacity of a screw conveyor falls off progressively as the axis of the casing is inclined. This is mainly because the dynamic repose slope surface of the material is unchanged and is limited by material carrying over the centre shaft by its rotation to fall back into the prior pitch space so the inclination of the screw flight cuts off an underside section of the material in transit.
