Screw Conveyor Sizing : Things to Know

The capacity of a screw conveyor is measured in cubic feet per hour. When calculating screw conveyor sizing, manufacturers look at the desired flow rate, the diameter of the screw (the part where the blades extend), the outside diameter of the center pipe, the pitch of the screw (the distance between each blade on the screw), and the trough ...

Sizing a Screw Conveyor

The first step in sizing a screw conveyor is to determine the diameter. 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 ...
