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.

The time is really dependent on the jar, the media size, how much media is in the jar, and how much material you are trying to mill. I do not mill aluminum, but for BP mill times vary between hours and 8 hours depending on the setup. I believe that German Black Head has a nominal mesh size of 200, but contains particles as small as 2µ.
Ball mills can reduce particles to nano sizes, the process is very important in creating powders used in hitech industries ( alumina). Ball mills are slow compared to other methods of grinding, it could take hours, for example, to grind all the particles in a clay to minus 200 mesh. Industrial mills seeking nanosizes might run 24 hours or ...
The one and only time I tried to Mill pure kno3 I got the rock hard balls. I put them in a mason jar in case I ever get desperate enough to break them up and use them LOL I had just made a batch of black powder with the same kno3 but I guess the charcoal absorb the extra moisture.
The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours. As the ball mill rotates, the lead balls will crush the chemicals together, forcing some of the potassium nitrate into the pores of the charcoal and sulfur.

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 ...
Milling Media Cautions In his book Ball Milling Theory and Practice for the Amateur Pyrotechnician, Lloyd includes a section on casting your own lead media. Some folks melt used lead automobile wheel weights or hardened linotype as the raw material for casting media.
Pyromaniac Full Member 79 posts Posted 20 June 2017 10:47 AM As far as I know, grinding mixed chemicals in a coffee grinder is extremely dangerous. Mortar and pestle might, work don't take my word for it though. Ball mill is the "safest" way to mill it to my knowledge.
A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.
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.

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.
