Floor angle and spout opening?

Floor angle and spout opening?

PostBy: SpurHntr On: Sat Mar 01, 2014 2:10 pm

I have somewhat of a ready made/built in coal bin room, poured 10" concrete walls/floor/roof.
The room is under my driveway.
This room was poured with the foundation, has a drain, is about 6x8x10', and the only opening is a steel exterior door(that I will remove and slide in some boards using some Z channel) and is at the same level(walkout basement) as our family room/harman super mag.
The price of bagged rice coal is nuts, even with me living right here in coal country.
And I am lookin at a 4+ ton year.

My questions ...
Has anyone figured out a "good" floor angle to keep the coal pushin to the front? - I don't like shoveling :)
And
Has anyone figured out the "perfect" sized hole one should cut out of one of the boards (at bucket height) to make the coal chute flow juuuust right but remaining not too vigorous that it is easily trap doored once my 40 lb buckets are full?

TIA

Todd,

I think somewhere on hear they mentioned rice needs 45* to free flow. That would really cut down on the amount of useable space or coal storage if you are looking at filling that space.

Then remember you would have to keep that angle on your discharge chute to the bucket. So depending on where you place the bucket and the length of the discharge chute, you might be another foot above the height of the bucket.

My outdoor bin has 2 bucket chutes on it. think I made the "hole" about 6" wide x 8" high and made a sliding gate to close it off. But the coal will get caught in the groove for the sliding door so sometimes the door will not close real tight.

Thx Rick
Yea, figured on some bin space loss, perhaps better to just leave floor flat and settle on a "reserve" ton at the bottom - emergency shoveling only! :lol:
I like your chute/hole measurement. Thanks! I expected a non sealed closure there.

If that was an old "cold room"...
You will want to have the slats behind an insulated exterior door...
Keep the drain active...
45* should work...
Make it wood so wet coal will dry...
Fill exterior vent with foam block...

Honestly. Not sure exactly what that room was designed for.
Will surely keep drain open.
Will surely place an elevated floor in it.
Wasn't thinking, of keeping the exterior door(current one rusted out bottom) but now might be thinking of replacing :idea:
No more vent...that was sealed off when driveway was black topped overhead...yes, thought of reopening it, but then I have water ingress issues into to bin(which is why door rusted out its bottom in first place) :mad:

Keep your flat floor,order more coal when flow stops,never run out of coal. ////// I have never posted pics,but look at those //// ,now think of them in a vertical position,make a "door" of these slats which you can pull at any level,one or all when level is low,they can be pushed back in to stop flow. If this makes no sense,maybe Freetownfred being a farmer has surely seen corn cribs set up with these & can post a drawing of it.

That would make it a Coal Crib...
Flat floor works if you do a yearly clean out...
If you don't the fines build up and it turns into a real project...
Trust me I work the Suburban Shallow Mines...
Pump spray and a mask will be required if you are lazy...
Go halfway and just angle the back half...

make the doorway opening with 2x12" boards and at the floor make the bottom board an opening with 3/4" plywood that will slide up,then open the slide up enough for coal and shovel to pull the coal out.There will be some spillage on the floor(just close the slide enough so there will not be too big of a pile.I made a enclosure to keep the spillage inside and coal hods also.the siliconed it to the floor to seal from water,moisture from spraying when chutting in for dust control.The pic. is not all that informative,but you can get a idea how it works.

Does this room have a wall against the house at all...
You could cut the concrete if so...
