Coefficient of Filling in Screw Conveyor

Nov 03, 2009· The fill of a horizontal screw conveyor is normally related to the nature of the bulk material, where the relevant factors are flowability, in regard to the absence of cohesion, and the contact friction value on the flight surface. 45% of the swept volume is generally the maximum fill level recommended for very easy-flow, low friction bulk products, such as grain.
