Screw Conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. It is important to understand, however, that as the angle of inclination increases, the allowable capacity
Read MoreThe actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing
Read More2020-12-14 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.

Mfg. often applies based on the situation: Tighter clearance between the screw and trough: This is especially true with granular, free flowing products such as dry, refined sugar. Higher screw speed: This increases the product’s forward momentum and reduces fallback. Shorter pitch screw flighting: This improves the relative angle between the each ...
