how to calculate or design of horizontal screw conveyor diameter pitch

component description Conveyor Screws

Stepped diameter conveyor screws consist of flights of different diameters, each with its regular pitch, mounted in tandem on one pipe or shaft. They are frequently used as feeder screws, with the smaller diameter located under bins or hoppers to regulate the flow of material. Stepped pitch conveyor screws are screws with succeeding single or groups of
