I have my Auger working well, so far one minor jam, which I caused just for testing to see how easy it was to unjam, The cooler you see in the video is a 100 Qts Coleman, I was able to fill it up in 8 minutes.

The one advantage of this system , is the fact that you can take the entire auger out of the bin, without touching the coal, I just tried it, to show a maintenance guy how it's done, just in case I am not around. The pressure on the auger caused by the weight of the coal is also adjustable, as it turned out, the coal bin holds about 8 tons.

There are many areas to improve on.

But here is the current list.

1: The power to the auger motor will be fed using relays
2: if the auger stops turning, the power shuts off in few seconds
3: A forward/reverse switch will be available to unjam the auger, in case of any binding
4: An oil drip system will be available as an option, to drop used transfat liquid ( which in essence is free ) to minimize dust, and for lubrication.
5:Powering the auger will be done by either a timer, on/off switch, or push buttons.
6:Couple of indicator lights

If you guys think of something extra, let me know.

For future searches;

Here are links showing my auger. Not a flex auger, but it might give you some ideas;

Bin to Hopper Grain Auger 30* up < Pics
COAL BIN Pics [page 39] - shows lower mounts

Not shown is the cover on the Kaa-2's hopper, with flex hose connecting it to the auger outlet snout. I'm still working on the boiler install, but I have tested the auger.

As most grain augers turn fast, I reduced the speed to apx 30 rpm. It was suggested that a fast auger speed would work well, but I was concerned about dust, as well as auger life, so I went with slow. The grain augers aren't made very "heavy". The flighting on mine is probably 18 ga, and the center tube is 16ga.

I believe that 45 degrees up would be doable. The gear reduction boxes are common on ebay.

Reviving this thread. There is some very good info on coal augers in this thread including different types, Helical, Grain Screw. Also a few places to buy augers. I will add that my Westfeild Grain Auger driven with a Yellow Flame 1765:1 gearbox and 1725 RPM motor, is alive and well. This system Delivers coal at a very slightly higher rate than the stoker burns it. That means I don't have to fill the hopper anymore!

There is one problem with my set up, It is difficult to keep coal over the auger inlet do to my coal bin design. I hope to correct that over the next few months.

Here is a neat video of a very interesting and very large coal moving auger. Not recomended for home use.



So, start planning next seasons auger project now!

Sorry, I posted the wrong utube video link above. This is the correct one.
