# Pounds of anthracite pea per cubic foot for coal bin?

### Pounds of anthracite pea per cubic foot for coal bin?

I've weighed a few 4 gallon bucket loads of anthracite pea at nominally about 30 lbs./pail. This comes to an overall average of about 7.5 lbs. of anthracite pea per gallon.

There are officially 7.48052 gallons in 1 cubic foot.

7.5 lbs/gal x 7.48052 gal/Cu-Ft = ~56.1 lbs. of anthracite pea per cubic foot.

2,000 lbs (one ton) divided by 56.1 lbs./Cu-Ft = 35.65 cubic feet per ton of anthracite pea.

Does 36.65 cubic feet per ton sound about right as a guideline in constructing a coal bin intended to hold specifically anthracite pea? Call it 37 cubic feet per ton to be safe.

If you do a search on here for Coal Bin Size, most of us use 40 Cubic Feet per Ton for sizing. You are pretty close.

So just take your L x W x H / 40 = XX TONS (Approx)

Sounds about good my friend... General rule of thumb dictates 40 Cubic Ft. per ton and I can say that provides some "wiggle" room... So your calculation sounds to be right on the money... I built my bin to accommodate 4 tons of rice sized coal and went with the 40 Cubic Ft. dimension, I ended up at 168 Cubic Ft. after final construction figuring I would give myself some extra space so its there if needed come delivery time... Well, I just loaded in 4 tons this past week and I have plenty of space left over, probably fit another 1/2 ton if I wanted to take it clear level full to the top... Again, your calc. sounds right on the money Larry!!!

I guess what I really need to do is put 4 gallons of water into my 4 gallon plastic pail and see where that level comes to. I was assuming that level to the top of the pail was 4 gallons, and that is probably not the case. There are likely more than 4 gallons of capacity in a completely full 4 gallon rated pail. Just like 55 gallon drums, which will typically hold more like 58 gallons if filled level to the brim. If 40 lbs/cubit foot is more accurate, then anthracite pea may be closer to 7.0 lbs. per gallon then it is to 7.5 lbs. per gallon.

Larry, if you were to build to the 40 Cubic Ft. per ton measure, you would find that you can fit more than 1 ton within 40 Cubic Ft volume of space... Either way it sounds like you have the right idea here... I assume you are interested in building a bin to accommodate an exact amount? If so, then I would highly recommend building to that exact amount you desire but add a little extra bin in there than what you need to be exact...

Guys, my old farm tape measuring tape don't show cubic feet--what does all that come out too in farmer tape language?

Nailing it down to exact cubic feet is impossible. Firstly different sizes take up more or less room.

Here's my old truck with buck on it:

If it were rice it would piled up some more. If it were nut coal you would barely see it, stove coal and it wouldn't top the sides. Secondly you have different densities, if that were really good coal from Hazleton it would't be stacked up like that and would be more even with the top.

If you use 4x8 sheets of plywood and build a bin 4x8x4, it will hold a little over 3 ton.

I took a 5 gallon bucket of rice coal to my vets office and weighed it on his ditigal electronic scale. Assuming it was accurate, it's about 34 pounds.
