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 ...

Since there is no center pipe to transmit torque, the shaftless spiral is designed to handle the full-motor torque load of the drive unit. Additionally, since the shaftless spiral has no center pipe for support, replaceable trough-conforming liners are used to evenly support the entire length of the rotating spiral. 5/8" THK.

9.15.1 Screw Conveyors. Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting.

KWS designs and manufactures two types of ribbon flighting – integral leg and post type. Integral leg ribbon flights are manufactured using the same process as sectional flights and the leg is integral with the ribbon. Post type ribbon flights use round bar posts that are typically located every 90 to 120-degrees around the diameter of the pipe.

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 ...
