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.
