Granulating our back powder for use in muzzleloading and pyrotechnics Mad Monk files: archive.org/details/mad_monk_... Music by John Fothergill from Pixabay Music by Charles Shomo from Pixabay
I normally use denatured alcohol and it's always worked well for me. I did try using acetone but it ended up very dusty and breaking apart too easy.

great video. Based on most videos ive seen, most people rub it through the sieve rather than push through. you started rubbing it anyways. as long as you rub and keep in motion the size would stay uniform. I learned alot in this video!

Thanks, glad you were able to get some info out of it. If you are really interested in learning pyrotechnics I would tell you to look up Ned Gorski. He has a website with tons of videos through his membership.

@jmohearn

This was mimosa (Albizia julibrissin) charcoal. I would suggest using Paulownia or willow though.

This one is 75% KNO3, 15% Charcoal and 10% Sulfur. I think that is what you are asking. 300 gram batch is 225 g KNO3, 45g charcoal, 30g Sulfur

Wouldn't you get the same results if you just rubbed one of those balls of moist powder through the screen?

You would probably get a similar result. I have found that this method I learned results in more unified grain size.

@Alibek_Mirasov 90% will probably work. I have only used 70% and I think this alcohol to H2O ratio works best.

Where did you get your screens at i cant find the size i need for 2f or 3f powder

I got these screens at woody’s rocks dot com. Search for screens on his site. I have not been able to find a 16 mesh anywhere though. You might try window screen and just count the mesh numbers per inch to see if it is what you need.

Need an aluminum tortilla press. Then instead of wax paper you use a flat plastic paint scraper to move it and press it through

That would probably work. In my case, I am trying to get the BP cake to a thickness of around 1/16" so when I press it through it comes out to around 1/8". It would be interesting to see if there was a way to calibrate something like a tortilla press to get a certain thickness.

That’s about how thick masa comes out. I’m gonna make some BP next week and I have a tortilla press so I’ll let you know or film it. Also found and aluminum and plastic grinder I may use for larger bits (I’m doing FFg, FFFg)

Also planning a variation on the CIA method making low pressure pucks using a coffee aero press and filter paper. Don't think it will improve density much put grinding them once dry might give more uniform granules (thats the hypothesis)@@jmohearn

Interesting, hopefully you get some good results! This process makes powder for pyrotechnics and I've found the size and density I get works well for lift and burst charges but I know its not as dense or as well mixed as what most people need for firearms@@wvcruffler123

@Alibek_Mirasov I do not use dextrin for this recipe. There are some recipes that do require it such as stars for aerial shells and rocket heads but not for the lift or burst charge.
