Most stump removers are 80%90% potassium nitrate, and it can be used to make black powder, but potassium nitrate will make better powder. 2 . Reply. David Cross says: ... Powders should be ground together with non sparking media for ball mill ie 1/2″ lead balls until powder is like flower. Add 3% dextrin as a binder slowly add water and ...

Using marbles as a ball mill for ball milling black powder has the potential to yield excellent results. The process is slower than using lead balls, but the results are the same. You should always use nonsparking materials such as ceramic or stainless steel when milling balls. Iron has a bad reputation for being corrosive due to its reactivity.

Claydog, the mill manufacturers don't make the machines for milling black powder. Commercial black powder manufacturers don't use ball mills for black powder. Ball milling black powder is the fastest, cheapest, easiest way to make it. With practically the entire amateur pyro community milling complete black powder, there's bound to be the ...

Had some mesquite lump charcoal at the house and a rock tumbler from our favorite cheap Chinese tool outlet. Ground up the charcoal and sifted it with the finest sifter I could find. Weighed out the components and put them in the rubber rock polisher can with some cast lead 38 cal bullets (no lube) to make an impromptu ball mill.

1 Purchase the items you can. This is one of those instances where the better quality the ingredients you have, the better quality product you will produce. The saltpeter and the sulfur can be found in most drugstores. 2 Make your charcoal. [1]

I have never had a, " little mill" but once you get a mill dialed in with the correct media and charge with (dry) chems it doesn't take long to mill powder to it's peak power. some have tested powder every 1/2 hour and found that a correct mill will get it done in 2 hours. That's about what I let mine go. give or take a few.

In my own experiments, I've found that I had to press the powder into "pucks" and crush and screen to get near the performance level as Goex. The economics of the home made black powder is very attractive if you don't count labor or equipment investment. The bought potassium nitrate and sulfur add up to about 3/lb.

Black powder can be made by milling the components singly and screenmixing together. Charcoal and potassium nitrate can be purchased premilled now, as well. Using a rock tumbler, you can make black powder faster by milling the charcoal and potassium nitrate separately. 3 component milling takes much longer to make good powder.

In doing research into black powder, you've probably come across several other methods. Mortar and pestle This can by all means be used to make serviceable compositions. It is potentially faster than a ball mill to make black powder, or other compositions. They are also useful to powder small amounts of chemicals.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

When we make use of an improved CIA method and proper raw materials, we can produce a suitable black powder product even in absence of a ball mill. Although its burning speed is nowhere near commercial, it´s good enough for many pyro applications (for lifting stars, comets, shells, making fuses etc.).

"The nice thing about shooting black powder is that commercial black costs about two cents a round, and homemade about a halfcent a round. " As the demand for powder grew in the Southern Appalachians, fairly large operations came into being for its manufacture. As Jim Moran told us, "Powder was made in this area. The big powder

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.

However, one step in the manufacture of black powder is running it in a ball mill to grind it into a fine powder. I was not in possession of a ball mill, and Independence Day was quickly approaching, so I decided to make my own. Ask Question Step 1: Parts and Tools Below are the parts and tools that I used to make this ball mill.

Loading the Mill. A cylindrical shell revolves around its axis to form the ball mill. Metal balls (or other grinding medium) are fed into the mill together with the components of black powder (potassium nitrate, charcoal, and sulfur) within the shell. Using a ball mill to make mixed black powder is a specific operation, but safety is crucial.

Milling Black Powder posted in Pyrotechnics: Just wanted to get a poll on varying options of most efficient yet safest way to mill black powder without a ball mill. I used to use a coffee grinder however the last time I milled some I resorted to a mortar and pestle instead, which was far too much work.

Making black powder The practice of making black powder (often abbreviated 'BP')is often oversimplified in textbooks. Merely mixing the components, potassium nitrate, charcoal and sulfur, does not result in real black powder. The mixture this obtained is called 'green powder' or 'polverone'. It bur

Here's a shot of some stainless steel media and ceramic media. 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.
