Shaftless screw conveyors do not have a center shaft or hanger bearings and thus have the ability to convey more materials. Typical fill rate for a shaftless screw conveyor is 30% to 45%. Keep in mind these percentages are for average consistent flows. On dewatered sludge apps the wettest %ds and lowest expected density should be used when calculating cubic feet/hour to get highest volumes to

16.10.2002· Does anyone know of a formula to calculate the loading on the thrust bearing of a screw conveyor? Yes this conveyor is a simple power screw used for axial movement of stone pulp in a stone mill. Mark's Handbook has a calculation for the power requirement but I can't find a formula for the thrust bearing load. Thanks, Doug . RE: Screw Conveyors GCPeters (Mechanical) 14 Oct 02 23:53.
