Powder you should add more media until you have a about 50 % of the jar filled. If your mill has problems with the weight, you also can use: Pieces of cut down brass rod. Non sparking stainless steel media (there are some suited types make sure to ask about this before you buy anything) Ceramic media either Alumina or Zyrconia are suited.
This method will only make slow is my method: Ball mill, soft wood charcoal (willow,balsa,eastern red ceder)are a must. Good potassium nitrate and sulfur. Powders should be ground together with non sparking media for ball mill ie 1/2″ lead balls until powder is like flower.
You must use 20 : 1 ball to powder ratio and milled it atleast 10 to 15 hours and make sure that mill does not get hot while milling powders. Measure the particle size and thephases using XRD and SEM.
I have been working on this idea for some time now. I should be able to demonstrate my screenmixed black powder within a week or two. The intention is to use a 3lb nozzleless rocket to lift a 6" ball shell. The burst will be the same powder. More of the same powder will be used to lift and burst shells.
20. Posted August 22, 2010. Milling until the BP clumps or sticks to the jar is a good thing. You had a lttle moisture, probably in the kn03. Grate the "balls" through a screen, dampen and rice. Or put them in a bucket and crush with the end of a baseball bat as if you would in corning.
The stainless steel must be sparkresistant, nonmagnetic steel in the 300series. Alloys 304 and 316 are the most common stainless steels of this type. Highdensity alumina ceramic media is the type I've heard of most often being used in ball mills. Stainless Steel and Ceramic Milling Media
IMO, magnetite wouldnt burn, since already strongly oxydized, rather it can be an oxydizer (some thermites are made with Fe304 instead of Fe203) but, as mentionned, it is ferrous, can surely transfer static electricity, that's why it's good to avoid this material at all costs in the charcoal, if ball milled as BP afterwards in a ball mill.
Having done black powder in a homemade cylindrical ball mill made of pvc pipe, and milling for hours at a time. I've had no issues using ceramic media. If you have it running the right speed, it will grind. It shouldn't be running so fast as to run up the side of the wall and drop from a height. Fluidized bed effect is what you're shooting for.
After ball milling treatment, the size of oyster protein powder significantly decreased and the powder became denser and more homogeneous in the first 12 min, which was similar to the effect on the ball‐milled soybean protein isolate and mussel protein (Sun, Wu, et al., 2015; Yu et al., 2018).

Do you need a ball mill for black powder? Proportions by weight are 75% potassium nitrate (known as saltpeter or saltpetre), 15% softwood charcoal, and 10% sulfur. These ratios have varied over the centuries and by country, and can be altered somewhat depending on the purpose of the powder.
Even in a ball mill with lead grinding elements, I would not grind the mixed ingredients. You have a large amount of powder, in a confined space, in a glass container (hmmm, shrapnel!). It's a disaster waiting to happen. Why take the risk, when it's just as simple to grind and ballmill the ingredients separately before mixing?
Place the bananas in the dehydrator and set the temperature at 135 degrees F. Make sure the bananas don't touch each other as they might end up sticking to each other. Usually, bananas take somewhere from 1012 hours to dehydrate properly. But you can check around the sixhour mark and flip the slices if needed. Step 5.

Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.

Overgrinding the combination might result in undesirable effects or risks. Safety Considerations. It is critical to take necessary safety precautions when using a ball mill to make black powder.

Where I live, you can't really buy black powder. I have heard the black powder created by ball milling is superior to that made with red gum.
