Designing Inclined Screw Conveyors for Industrial

2017-2-21  When designing an inclined screw conveyor, it is important to understand how the construction features affect the flowrate or conveying capacity. Selecting the proper trough type and screw pitch will greatly increase the conveying efficiency. Two types of troughs are typically used with inclined screw conveyors;

2021-6-19  The design is a bit involved and these items should be taken into consideration: More horsepower is required for Inclined Screw Conveyors: This is due to both lifting the product and “reconveying” product that falls back. Hangers should be eliminated: They create a “dead flow” area that is emphasized with inclined conveyors. This often results in the use of longer screws which require their own design

Inclined Screw Conveyors

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 of a given unit rapidly decreases. A standard Screw Conveyor inclined
