Performance evaluation of a new screw conveyor for metal

1997-7-1  The unconventional screw conveyor tested allows all kinds of metal swarf, which can vary widely between fine particles (dust in dry condition or sludge when wet) and long spiral or helical ribbons, to be transported satisfactorily. Tests were carried out to investigate the influence of assorted metal swarf types on screw performance when the device works in steady, near clogging, dry or wet conditions.

Screw conveyors are very effective for transporting dry particulates, giving good control over the throughput. Despite their apparent simplicity, the transportation action is very complex and designers have tended to rely heavily on empirical performance data. In this paper, we use the DEM to examine how variations of particle properties influence the performance of the screw conveyor.

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.

Right finish level for screw conveyor system ensures

Conveyor performance The secret lies in the right combination of the screw and the body, which both help to convey the product. The screw pushes the product forwards, but the amount of movement is also based on the type of body. In short: conveyance of the product is the result of the combination between movement and friction.
