The horizontal screw […]

The throughput of an enclosed screw conveyor is influenced by the rotational or vortex motion of the bulk material during transportation and the degree of fill or "fullness" of the screw. As the rotational speed of the conveyor increases, the rotational or vortex motion decreases up to a limiting value, making for a more efficient conveying action.
