A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a flighting , usually within a tube, to move liquid or granular ...
The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are running at 30-45 trough fill level.
There are certain parameters for sizing a screw conveyor. The capacity calculation takes into account the outside diameter of the screw, the outside diameter of the pipe or central axis, the screw pitch and the load contained in the trough. The calculation determines the capacity in cubic feet per hour that will be handled with each revolution ...
