Coal Bin Pictures and Designs

Considering you are having some coal fall through the grates, that is reasonable. Perhaps you can shake a little less and have less unburned coal pass through.

rob, just this summer I have installed a master grate shaker(shakes all 3 at the same time) and have done much better this year. I will be comparing STCP and UAE this year and make a new thread. Dennis

My 5 year old boy loading the buckets. I built the bin this summer. 4x4x8 holds 3 ton, but I only have 2.5 tons of nut in it. I wish I had ordered a full 3 tons as 2.5 is not going to last the winter at this rate. Material cost was $283, 4x6 skids & paint not included in the price. I went with cheap 3/4" cdx plywood for the floor, when it rots out I'm going to buy one of the local fiberglass bins for $400.

Here are some pictures of my new 8x8x6 bin. I built it out of 3/4 plywood bolted to pressure treated 4x4s. It should hold about 9.6 tons minus the area for the auger's doghouse. Having automated feeding via the auger to the boiler is a beautiful thing! One side is supported by my concrete foundation; but, I was a little concerned about the other three sides---so I added three rows of 2x6 lumber to the base on the unsupported sides. I also ripped 12" wide 3/4 plywood and screwed this plywood to the joint between the 4x8 plywood and 2x8 plywood.

Loading the bin was interesting. I have a JD 4310 compact utility tractor w/430 loader w/6 foot bucket. I fabricated a "funnel" out of two sheets of 3/4 plywood; and, dumped the coal into the bin via the chute through my garage. I didn't take any pictures of this part of the job... I was too busy getting it done! We're all set for winter now!! Bring it on winter!!!

Dewey, that's one sweet bin!

Super bin Watkins.

Super boy Northern.

Nice design on the bin Murdoc. Very good idea for disassembly.
I had to take my old bin completely appart when I moved this summer. The old bin was on the garage floor. The new house has a full basement so I built a huge bin down there. \
I like your chute. I built a plate steel hopper door just high enough off the floor to empty into a skuttle. I could use a short chute added to it. Good project for next summer.

Great job Dewey cant wait to see it in person

We're figuring it out as we go but I think we'll put 1/2" plywood over the bottom then frame in the sides. The width is 8', will this hold ~2 ton without more support? The bottom is framed 16" OC.

It probably could use another pair of blocks in the middle.

Was afraid of that. That grassy bit in the middle there isn't exactly level with the concrete. Maybe putting the middle ones off-center will still get the job done.

Ok, I but an additional footer in the middle, hoping that will give me a little more support. We finished the bottom, back, and sides tonight as it got dark. More later.

Here is the start of my outdoor coal bin. When finished it should hold close to 5 tons. There is about 1.25 tons, in the first bin, the second bin will get filled when I am finished and the third bin will be my workstation to fill buckets. I will side it to match the shed and house in the spring and clean up the job site before snow falls so the working area can be snowblown. The top has a 2' x 2' fill hatch for each bin. The construction is 4"x4" PT corners and center posts with 2" x 4" PT joists 2' OC. The sheeting is 3/4" plywood. The entire bin is 12' by 4' ID, and sits on a 4" rebar reinforced slab. Comments/criticism welcome.

Finished enough of the bin to take delivery. Unfortunately the back of the truck is too low to dump into it.
