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.
In this video, I show a comparison in slow motion of the burn rate of the black powder before and after it went in the ball construction of the ball...

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.
It influences the final particle size and the quality of the black powder. Longer grinding durations and fasterrotating speeds produce finer powder. 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.
All he had to buy for this project were the 5/8″ steel balls and the casters. The mill can also be used as a rock tumbler, though the bottle isn't quite water tight asis. He does not ...
Explosive Manufacturing, Ingredients, Gunpowder: Manufacture of black powder was accomplished originally by hand methods. Ingredients were ground together with a mortar and pestle. The next step was to use crushing devices of wood (wooden stamps), also operated by hand, in wooden or stone bowls. The stamping process was gradually mechanized and, about 1435, the first powder mill driven by ...
December 28, 2022 by Pao. The simple answer to this question is yes, granulated black powder burns faster than other types of black powder. This is because granulated black powder is more finely ground, and thus has a larger surface area exposed to oxygen. This means that the powder ignites more easily, and burns more quickly.
February 16, 2018 How to Use a Ball Mill Safely and Effectively I have some lump charcoal that just came out of my retort after I cooked it, and I want to turn it into airfloat charcoal. Or, the directions say to ball mill my rocket fuel for an hour. An article tells me to ball mill my star composition prior to pressing my stars.
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.
Page 1 of 4 Air Float Charcoal Black Powder posted in Pyrotechnics: A few weeks back I tried making some ball mill black powder with the usual ratios. I used Sulfur found at a garden supply store, Air Float Charcoal, and Technical Grade KNO3. I milled it for about 2 hours or so and then added 5% dextrin and granulated it. Its surprisingly underwhelming.
1 6 Lb. Rotary Ball Mill. 6 Lb capacity DOUBLE Barrel ball mill. Perfect size for milling 2 different comps at once in separate drums. (2 barrels measures " high x " in diameter). Grind most materials into a fine powder in just a few hours. Includes 2 single 3 lb. Neoprene barrel with quickseal, leak proof closures (spark ...

Mill all three components together to integrate well. The actual milling time depends on the efficiency of the particular mill. 23 hours should be considered the minimum with typical amateur ball mills. Some choose to ball mill the Sulfur and Charcoal together separately from the Potassium Nitrate for a large part of the mill time.

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).

For approximately 45 you will have a functional ball mill and media, capable of creating BP in 812 hours. People have recommended going as long as 24 to 48 hours using the same setup. One will have to do some tests to determine when the quality of their BP is up to snuff.
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.
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?
thanks Randy on March 24, 2013 at 1:34 PM Good article Harry, Now you should investigate the alternative way to make superior Black Powder. Those prilled Potassium Nitrate crystals will dissolve in heated water and so there's no need to premill.
Here are two reasons for using lead balls: Reason #1: They will never spark and cause your ball mill explode. Reason #2: Because of their high density, they will do a much better job of pounding the powder. boredvamper • 10 mo. ago. Not arguing that it's heavier but none of the ones I mentioned will produce a spark.
Gather the cloth strainer to remove the retained solid matter; wring out the resulting "ball" and squeeze it well to remove as much moisture as possible. 14.) Line a baking sheet with newspaper and put in the powder retained in the cloth strainer; break up the ball by hand and distribute the powder well on the paper.
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. I am planning to buy a 6 lb rock tumbler from HF and modify it a little. I live in a neighborhood, so I don't have that much room to distance the mill from buildings, and want to be safe.
In this video, I start by showing that homemade black powder doesn't burn very well if the ingredients are only ground separately with a coffee grinder. Then...
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.
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

Pyrotechnics. ball milling black powder. hondo. ActionTekJackson. Simoski. Arthur. ×. I have been ball milling my bp for a year now, and lately my powder is clumping up in the mill, it use to come out nice and fluffy. Whats happening, is the potassium nitrate or sulfur absorbing moisture and causing the clumping problem.
Luckily, O2 got into your ball mill or you may have had a hot mess on your hands. It is widely recommended that you open the mill jar every few hours to allows O2 in at intervals. Oh no, the powder was not milled for 3 days without being allowed to vent.
What temperature does black powder burn at? Black powder has an ignition temperature of approximately 500 °F and is federally regulated as a Class A Explosive. How long should you ball mill black powder? Standard length mill times are half an hour for individual chemicals, and 24 hours for highquality black powder.
