DIY Ball Mill for making fine Black Powder

This simple Ball mill made from a Plastic Jar, Rubber Band, Scrap DC Motor, Cardboard, Rocks. i made Black Powder with it in another video from natural nitrates growing on my wall.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
The grinding works on the principle of critical speed. Critical speed can be understood as that speed after which the steel balls that are responsible for the grinding of particles start rotating along the direction of the cylindrical device, thus causing no further grinding.

Wow! i love how simple it is!!!!!❤❤

Idk if using stones is a good idea, becasue i don't know if they won't spark, lead or glass balls might be better

Your idea is very genius idol, support from 🇵🇭

Thanks!✨

You can use this machine to make the ingredients for thermite.

i'm gonna do that!

I subbed because i like when someone makes simple, yet very useful things. I hate when they say somethings homemade, then use 3D printer/lathe to make it.
Have you tried this with Al powder? Use ball from ball bearings, different sizes should be better, put small balls made out of Al foil and it should be great

Thanks! i hate those channels too, often the things they make don't even work properly with all those fancy stuff. i tried aluminium but it needs a bigger container (&bigger motor) so the balls fall with more energy, its not powerful enough.

this thing works well for me, mine is only slightly different

Nice little mill but maybe dont use rocks as your grinding material because they could spark when grinding.Use ceramic or hardened lead instead.

[@aufoslab]

marbles work great too...
I couldn't make aluminium powder with it because the balls are not heavy enough and the diameter of it is only good for black powder, aluminium powder needs at least 30 cm diameter with steel balls.

Brass is a good option as well. Does not spark, weights a lot and no product contamination.

Please make a video on flash powder and how to make aluminum powder as well as please

[@user-iz7ge]

Put the smallest pieces of aluminum foil and charcoal in a ball mill with steel balls, nuts etc. you'll have to mill it for like a week or something and open it every day so it want light up after a week of milling, the aluminum to charcoal ratio should be 95 aluminum to 5 charcoal, charcoal is to prevent oxidizing, flash powder is from what i remember 50 parts potassium nitrate, 40 parts aluminum and 10 sulfur, NEVER BALL MILL OR USE A MORTAR ON FLASH POWDER.
