2021-10-3 Warning : It must be noted that those formula aim at giving an idea of the size of the screw conveyor (which means its diameter) and the speed at which it will operate, based on some assumptions and some design decisions (choice of screw pitch, inclination). The formula can also be used to roughly check the capacity of an existing screw feeder.
Read MoreScrew 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 More2014-7-14 In inclined screw conveyor, as we increase the angle of conveyor from ground, its capacity decreases. Here inclination factor comes in play. Say, if angle of inclination is 15%, inclination factor is 0.75. It means, conveyor capacity will be 0.75times of horizontal conveyor capacity. Now, my question is how this inclination factor affects motor ...

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.
