MoreCAPACITY of a screw conveyor is determined volumetrically. If a given weight of product is to be conveyed in a specified time, the loose bulk density of the product must be known to determine the actual volume to be conveyed. Most products have a lower bulk density when agitated or aerated during conveying than when at rest. The lowest bulk density must be used to calculate the volume to be ...
