Hi,

I was asked to design a screw conveyor (if this the correct terminology)

The screw is a spiral flat, welded around a shaft.

The parts are made of disk with a hole in the middle to make one part of the screw.

The parts are then welded together around the shaft.

Please see the attach file for a better understanding.

The question marks in the drawing is the question...

Your help will be appreciated
