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 ...

Conveyor Component Selection
Radial load is negligible at the conveyor tail shaft. However, drive ends (unless integrated with the conveyor end plate) are subject to radial loading due to overhung drive loads, such as chain sprockets or shaftmounted speed reducers.
