Prediction of screw conveyor performance using the ...

Screw conveyors are used in agriculture and industry for transporting or elevating dry particulates. Despite their apparent simplicity, the transportation action is very complex and designers have tended to rely heavily on empirical performance data.

18 GREENID SCREW CONVEYOR PERFORMANCE

screw conveyors and compared their results with previous work and empirical equations. Owen et al. (2003) introduced the use of a periodic slice model to explore the performance of a long screw conveyor. Cleary (2004) used DEM to study draw down patterns from a hopper by a 45° inclined screw conveyor. This work was extended

Screw Conveyor - an overview | ScienceDirect Topics

Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting.

Design and performance criteria for screw conveyors in ...

A theory is presented to predict the performance of screw conveyors of any specified geometry. The influence of the flow properties of the bulk material on the conveyor performance is illustrated.

Development of Screw Conveyor Performance Models …

The most significant parameter affecting the volumetric efficiency and specific power was the angle of inclination of the conveyor. It accounted for 50 to 60% of the variation in the data. These models may be used to study parameter interaction effects on the conveyor performance, which may be useful in the design and selection of screw conveyors.
