Designing Inclined Screw Conveyors for Industrial Applications

Feb 21, 2017  Certain parameters are required for sizing a screw conveyor. The capacity calculation for screw conveyors takes into account the outside diameter of the screw, the outside diameter of the center pipe, the pitch of the screw and the trough loading. The calculation determines the capacity that will be conveyed with each revolution of screw rotation.
