Still handy to have. If your getting bulk delivery into a bin, you may not have to sift out fines every year, but even with clean coal, eventually there will be a build up of fines.
When coal was used more, it was not uncommon to see two coal bins side by side. One bin was used up to get down to the bottom so that the fines could be cleaned out. The other bin would be left full and waiting to be used next. Alternating that way, the bins got emptied each year and cleaned of fines. If let go, the fines will accumulate reducing how much coal the bin will hold.
I built one 6 ton bin, six years ago. Each year I've been ordering more coal than I use, never getting the bin down to the bottom. Last year, I had accumulated a years worth, so I didn't order any coal. I wanted to use up what I had and get down to the bottom of the bin to remove whatever fines had accumulated. Turns out it wasn't as bad as I thought. About 4 five gallon pails worth.
