1. Only mill KNO3. Never use a more powerful oxidising agent. 2. Never mill colour comps. 3. Make sure you use LEAD or other non-sparking media. 4. Ensure the mill is away from the house - a garage may be best (without car!) 5. Dampen the mixture - ensure that it's damp at all times - approx. 8% water. This would mean that for 100g of

At the same time, the entire mass will be reduced to a super fine powder. The longer the Ball Mill runs, the stronger the Black Powder will be. A general rule of thumb for all pyrotechnic mixtures is " the finer the powder is, the faster it will burn ". ONLY lead balls can be used in a Ball Mill as they are completely non-sparking. ONLY Black ...

If a ball mill is used, spark free ball mills, such as lead-antimony are a must. Another tip would be to add a little water, to reduce the chance of ignition. Other volatile solvents can also be added, though preferably non-flammable ones. The best type of charcoal for making gunpowder is made from softwood, such as willow.
Screen the chemicals together and pass several times through mesh screen. Place the green mix into a ball mill with non-sparking milling media . It should be milled for at least 3-4 hours. Summary It has many uses including prime, dusting, a general ingredient in some compositions and preventing stars from sticking together during manufacture
Ball Mill Safety Discussion Part 2 - posted in Safety: If you intend to make black powder with your ball mill, I recommend against high-alumina media for a couple of reasons: 1) Theres a nagging suspicion that it sparks -- this may be due to its EXTREME hardness, which causes impacts of very tiny area, and therefore of immense forces (per square area).
I am getting a ball mill in the next week or so and was going to order some proper pyrotechnic grinding media online. In the meantime will medium size lead fish sinkers work well as non-sparking media for milling black powder, are they safe to use?
in ball mills. As so many things in pyro, there are opinions all over the place. use brass, non sparking and hard do not use brass, its copper content is an unacceptable risk in pyro (same for bronze) use lead, non sparking and heavy do not use lead, it is soft, wears, contaminates your grind and is poisonous use ceramic, it is hard and wears well
When it reaches a certain thickness, it will cause the surface of the stator coil. A short-circuit discharge situation has occurred. When the short-circuit phenomenon occurs many times, the insulator of the coil will be damaged, causing the phenomenon of sparking and breakdown, causing the ball mill to stop running.

Fig. 3 shows X-ray diffraction patterns of a powder mixture of 3Ni-Al system after HEBM in a planetary ball mill with durations of 1, 1.5, 2.5, 3.5, 4.5, 5.5, and 10.5 min. As can be seen from the figure presented, an increase in the HEBM duration is characterized by a change in the shape, intensity, and width of the diffraction peaks.
During arc (or spark) discharge milling (above about 0.1 MPa gas pressure), the conduction path is through the balls, the ball–chamber …
Here's a shot of some stainless steel media and ceramic media. The stainless steel must be spark-resistant, non-magnetic steel in the 300-series. Alloys 304 and 316 are the most common stainless steels of this type. High-density alumina ceramic media is the type I've heard of most often being used in ball mills.
The grinding steel balls are 9 mm in diameter and the ball-to-powder mass ratio was 20:1. Batches consisted of 10 g powders and were milled using a high-energy planetary water-cooled planetary mill AGO-2 (ISSC SB RAS, Russia). The mill rotating speed of the AGO-2 was equal to 912 rpm, which corresponded to 2220 rpm for bowls.

The biggest danger from ball mills is the danger of explosion. Never ball mill BP indoors and always use non-sparking milling media. I use50 caliber lead balls but I also have used brass chunks cut from 1/2 to 5/8 bar. Don't use marbles or steel balls of any sort. I personally think ball mills are safe if used to mill BP (not other propellants!);

However the ball mill jar is made of steel and I already know having no metal inside your ball mill other than lead balls is kind of a big no..... Just doubt checking that a steel jar is a bad idea. Would it be better to make a PVC one that also can fit inside the mill or can I line the inside of the steel jar with something else to avoid sparking.
