Ah, maybe this is a good time to go over some of the engineering design details that apply to tumbling. There is a parameter called 'critical speed'. It is the rpm at which a particle will stick to the inside of the drum just from centrifugal force, and there will be no grinding action at all. This is where your drum goes quiet and for a 4" ID drum, it is above ~110 RPM. To get the best grinding action, you want to maximize ball on ball 'nipping' as this gives you the most extensive grinding action throughout your media volume. You do *not* want the media to free-fall and produce a pounding action, you want rolling and sliding action. 85 RPM is close to ideal for a 4" mill jar. A bit slower is fine, but do not go faster. There is a demo video here: kzitem.info/news/bejne/rWypzXuOkYuVeIo The Harbor Freight rock tumbler only runs at ~45 rpm, so there is a lot of sliding action, but slower than appropriate for BP. But then, it was made for rocks and meant to run for a week or more at a time. Now, a few words about media: Balls are not ideal for producing powder. They are most appropriate for reducing coarse material to fine. To reduce fine to airfloat dust, a different shape is optimum. You want to adopt techniques that are similar to what is used for grinding paint pigment. Trapezoidal prisms work well because they maximize the contact area for sliding action. I have been using ceramic trapezoids that I got from Winona Van Norman. They list on ebay. (The ceramic media from HF is junk.) I have found that they work nicely in the HF tumbler and their lower density than brass is not a problem since they are still more dense than KNO3. They will just be a little slower and gentler than brass. If you want to use Yellow Brass (and this is a very good choice) get some square stock, either 3/8 or 1/2" and cut the pieces at a bias angle of 45 degrees with a length equal to the side dimension. This gives an effective trapezoid shape that packs much better than cubes or balls, giving greater contact area. Make sure your media has smooth surfaces and edges. If necessary, pre-tumble it with some fine aluminum oxide grit (>100 mesh) until it is nice and smooth. Sharp edges will tear up the inside of your mill jar. Now there is the matter of how to fill your milling jar for best action. You want your media to occupy roughly half of the volume of your jar, not much more or less. Now, and this is important... Add your material that you are grinding so that it only occupies the spaces in the gaps between the media pieces, coming up to just a little less than the volume of the media at the very most. When you shake the powder down into the media, it should not cover the top layer of balls, but should occupy only about 90% or less of the gap space between the media pieces. You can use a batch size much less than this and it will still work fine even down to about 20%. This will give you the best grinding and cutting action in the shortest time. If you use a different fill, it might still work, but might take longer to finish.

Fired .45 ACP cases filled flush with with melted wheel weight lead alloy and roll crimped make fantastic, cheap to free tumbling media. Cylinders are better than spheres in my experience.

Just in the last month or two I was thinking about the use of lead in the ball mill and that little bits of it would be wearing off into the powder as it tumbles into each other, so that lead would be in the smoke and breathed as your firing, and I do like the smell of black powder, but I like all my brain cells to be lead free, probable I lost enough as a kid when all cars used gas with lead in it.

That's clever..... I scratch built mine using odds and ends. I used 3/8" spindles with 3/4" rubber wheels off an old document transport system pushed on to them. The spindles are on sealed ball races driven by a 1/3 hp motor off an old washing machine. Chassis is 1/2" MDF screwed and glued together, I made it in an afternoon about five years ago. My milling balls are pure linotype metal .69 calibre, and the jar is a plastic drum that has soda blasting medium in it... just the right size. It is coated with a couple of layers of duct tape for wear resistance. No signs of wear yet. Actually, I see no reason why a steel drum would not be OK with either brass or lead balls... nothing to spark in there, and less likely to have static problems in opening. Still meanwhile my plastic drum, is working fine. About 70-90rpm seems about right, making the balls climb up just past the vertical before dripping back on to the powder. I usually mill for about 6 hours or so, but might increase that a fair bit as the longer I mill the faster the powder seems to be. There's some weird stuff happening to those grains in the mill at the atomic level that seems to take time. Did you ever read about the ball mill that used iron filings and very hard steel balls and they milled it for weeks and the properties of the iron flakes after that treatment were astonishing. I think we are seeing similar things in our little mills. The factory at Waltham Abbey in the UK used cast iron wheels n an iron track. The wheels weight several tons and squished the powder grains on the circular track. The process was done dry I believe. The factory used to make all of the powder for the British military, but was destroyed in a explosion many years ago and now, ironically, the British military get their BP from Germany... 😀

Pricing solid brass balls that are 1/2" runs around $15 for 10 so it would be between $250-$300 for 200 in brass, but I agree, brass has ALWAYS been used for black powder. Flasks have been made from brass as far back as the 1800's and they're still making them now because they are non-sparking.

Jake.. having a bit of trouble w my treadmill ball mill. The next time you’re going to start milling could you measure the distance: center of front roller to center of back roller? I know it seems trivial, but I watch yours spin like a mofo at 1.7: and at 2.8 mine doesn’t seem to spin even that fast. Theorizing I might have the rollers either too close, or two far apart for optimum spin. Using strips of 180 grit sandpaper glued to the roller under power. I don’t weld so I mounted mine on wood and bolted to the frame so it’s a major endeavor to change it for experimental purposes so I was just curious about your setup. I now have everything but the screens, so I’m ready to give a wack.. I’m an old guy, so I hope you bear w me and all my questions 😬

Critical speed of a ball mill is the point where as the mill is sped up, the contents no longer begin falling as they reach 12 o'clock. This is also the speed at which the mill stops making noise. Taking the mill to this critical speed and then back to 75% of this speed will be about correct. You can see this in a windowed clothes dryer. If you can tumble briefly with media but no powder present, tumble without the cap on the jar. The media should remain on the walls until about 45 degrees before vertical which should also be about 75% critical speed.

5:30 This looks like it can be done WITHOUT a welder... A couple brackets and a metal drill and a cutting disk is all you need for this project. Welder makes for a quicker tidier job, but if you don't have one brackets would do for the joining. Thanks btw, this is a great idea with the treadmill. It's got "mill" right in the name.

The commercial mill I saw was steel. I never saw it in operation. They stopped it to add about a ton of charcoal and sulfur 3:2 mix through a large side door. Holes on one end let hot air in. The other sucked out the dust. Only the fine dust was kept and coarse material was put back in with the cannon balls. I never heard 3" cast iron cannon balls in a steel drum. It isn't something that you could mimic in a residential area. But it mixed the two parts together before blending with wet potassium. Slurry was made by weighing an amount dry then pulverizing it with steam. The slurry was mixed with the dust using air. That dough was augered to the puck press. As with many plants, one day, it burned. They never rebuilt in Woodinville. Too many houses in the 80's were moving in. There was an underground rocket fuel plant right next door. What genius did that?

Wow, that mill was spinning fast. Is the media going to still be able to do its work???

Is aluminum a safe alternative to brass? Talking of course about sparks.

you might try cutting a cross section from a motorcycle inner tube , try different size tubes for a stretch fit , i couldn't get replacement belts for my bench top drill press so cross sectioned a car tube ( although i'm told they dont use tubes on retreads no more ) not sure if bikes still use tubes , my WLA does ,thanks for sharing , cheers big ears from down under

i used to use pure nickel as a tumbling media, it came as one inch square pieces that were about 3/16ths inch thick.

I used a treadmill as a big tumbler on a 1gal pickle jar. I just clamped a 2x4 across that deck. Then just set the jar on the belt and the 2x4 keeps it rolling.

I do have a Thumbler's Tumbler that I use to wet clean brass. Being I have this, would you still recommend the treadmill ball mill? Also, what is the ratio of brass balls to XX weight of powder do you recommend? I'm thinking I would do 8oz powder at a time. Thanks for a great video!

Absolutely. I fill my jar roughly 1/3 full of brass balls and I run 200grams of powder at a time. However, I’m confident it would do 300grams easy.

I haven't tried making powder as of yet. He stated that using lead balls makes for dirty powder. What if you used powder coated lead balls? Would that make for a cleaner milling process? Just curious.

Couldnt you just melt some lead and pour it into Brass cases and then squeeze the end of the case with a vice to keep the lead inside ?
