Jan 27, 2016 I have been working on a screw conveyor and, of course, the flights. I was told that using the Coil tool in Inventor would not allow the flight to be unfold as a sheet metal part. After a bit on research online, that seems to be a common problem and many people are drawing the flat pattern separately. ... The helix is drawn using the 3D Sketch ...
May 10, 2018 A standard screw conveyor is normally fed by another conveyor and the amount of material being discharged is directly proportional to the amount being introduced at the inlet. In contrast, the inlet of a screw feeder is always 100-percent or flood loaded and typically mounted directly to a storage device such as a hopper, bin or silo.
