Changing Auger Diameter
Starting out at 4" dia flight for 4ft then going to a 5" dia flight might pack the power too much. ■
Re: Changing Auger Diameter
Why is your screw discharger on a decline, not normally necessary is it? 
How well will it work, I might have graduated the pitch and/or core diameter along it's length inside the bin in an attempt to discharge the bin from along it's length. If not, the tendency will be to discharge the back first, leading to the possibility of arching over the screw at the front as it's only 4" diameter. Outside the bin I might have had the first foot at 4" in a tube before increasing to 6" maybe in a U trough. ■
Auger Dia
Be advised, a revision has occurred: This is now a 20foot long auger w/ 9ft in bin. We will need hanger bearing at the 10’ mark or (a bearing shoe on flight, I like). A coupling before, after or during this section as well w/external sleeve or bolt pad.
The declining angle is necessary to avoid obstacles that are not moveable, both above and below, it just work out that it was a strength path to the feed belt. The output location of the bin auger is right above a transfer feed belt. The last 2’ of the auger is a very tight area, there is only a 8” or 9” opening to thread the needle there to the feed belt target area.
I see your point in U trough at the last section of auger to release any packing occurring through the pipe section for a better control count on volume, maybe last 3’ section!
Having a graduated pitch in the first 8’;
1. Let say a full pitch at 3” dia the first 3’
2. then full pitch the next 3’ with the same 4” dia
3. and the next 3’(inside the bin) is full pitch at 5” dia.
4. The next 4’ in tube is still full pitch at 5” dia.
5. then the next 4’ in tube is 1/2-pitch at 5” dia.
6. Remaining 3’is U trough at 1-2 pitch at 6”dia.
Do you think a more graduated? It does look more and more like we will also be trying to push the rope here with a hydr motor at bin end. ■

Changing Auger Diameter
A debate is on
This is a 12ft. auger in portland cement.
The first 8ft. of the auger that is inside and is a 4" flight (1to1 pitch)in a trough.
The last 4ft of auger is tubular at 6"dia flight (1to1 pitch)
yes, it will wook ,but how well when your are at only a 1/4 yd left in bin?
