Screw Conveyor Design Calculator
Description: Conveyor Capacity represents the volume of material that the screw conveyor can handle per unit of time. It is calculated by taking a quarter of π, multiplying it by the square of the Screw Diameter, and then multiplying by the Screw Speed and Fill Factor. Variables: Screw Diameter (D): The diameter of the screw shaft. …
Screw Conveyor Shafts
A screw conveyor tail shaft is the shaft at the end of the screw conveyor, opposite the drive shaft and is used to support the screw. The tail shaft is supported by either a flanged or pillowblock bearing. A tail shaft can be hardened through the seal area to reduce shaft wear and increase service life. Tail shafts are uniform in diameter and ...
