Mill all three components together to integrate well. The actual milling time depends on the efficiency of the particular mill. 2-3 hours should be considered the minimum with typical amateur ball mills. Some choose to ball mill the Sulfur and Charcoal together separately from the Potassium Nitrate for a large part of the mill time.

60 % finest Potassium Nitrate. 25 % very fine bright aluminum, forexample the 999, from the Indian MEPCO-factory. 15 % sulphur + 1 % boric acid. Mix only Potassium Nitrate, sulphur and boric acid and mill it like Black Powder, then sieve it and add the aluminum. Not so easy to ignite, but stronger, like a Barium Nitrate flash.

Posted July 5, 2012. I made some black powder yesterday with a ball mill... this is the burn test. Burn starts somewhere around 3s and ends before 4s, less than half a second. Used 75 Potassium Nitrate, 15 airfloat willow charcoal, and 10 sulfur. Ball milled 75 potassium nitrate + 5 charcoal, then 10 charcoal and 10 sulfur.

With this kit and a ball mill you can make every kind of black powder from superfine meal powder to 2FA lift powder.

Whether you are making 1lb or 10lb the breakdown will be the same 75% Potassium Nitrate, 15% Charcoal and 10% Sulfur. #Step Two. Next mill or grind your saltpeter. Most recommend doing this in a ball mill but I wanted to do this all by hand to get an idea of how it would work without conveniences. #Step Three

Having given a warning about avoiding milling potassium nitrate and charcoal together, I need to elaborate on this point. Generally a potassium nitrate/charcoal mix is more likely to ignite than a potassium nitrate/sulfur mix. However, mixing a small amount of charcoal with the po-tassium nitrate is regarded by some as safer.

I would make nozzled rockets, using 60-30-10 as my formula. I'd use a bullet grinder to reduce my charcoal, and screen it through 40 or 60 mesh, using everything that passes. Assuming the potassium nitrate is crystalline, I'd dissolve it in the smallest amount of boiling water I can use. I'd then add the charcoal and sulfur, and mix it well.

A ball mill is a rotating drum with dozens of lead balls inside. 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 ...

You could use the CIA-Method. That means you mill the charcoal and the sulfur without the KNO 3.. Than you dissolve your Nitrate in boiling water, add the milled C and S and precipitate the KNO 3 with ice cold ethanol.. This process makes a very fast powder, and you don´ t have to mill any explosive composition, however it is labour …

5lb Potassium Nitrate Milled The most extensively employed oxidizer in pyrotechnics. It used for a wide variety of applications, the most important of which is in the manufacture of black powder. Potassium nitrate is a white powder or long needle-like crystals before being milled to a fine powder.

Unless you have a really good reason do not skimp on mill time even though milling ingredients means three times the milling time. PVC as a ball mill tumbler. I built my own ball mill and built PVC tumblers (see pic) out of 4" PVC tube and fittings that I use for oxidizers (mostly Potassium Nitrate), Charcoal, and BP - 1 tumbler for each.

-If you would like to, ball mill your potassium nitrate using steel or high-alumina media. -50% Magnesium/50% KNO3 makes a pretty sweet flash powder. Ball mill the Mg and KNO3 separately for excellent results.

Potassium nitrate granulated has a chemical formula KNO3 and is known for its high purity, ranging from 99.4% to 99.7%. ... put it in the ball mill for 8 hours, granulated it, and then let it dry. That batch of bp ended up being the best I've ever made. I'm giving this one the normal 10/10! Rated 5 out of 5.

In making black powder, I've found that a material charge of 15 ounces of potassium nitrate, 3 ounces of airfloat charcoal, and 2 ounces of sulfur produces the most efficient quantity of BP mill dust.

Typically, a small coffee mill can efficiently grind about 3 ounces of the potassium nitrate at a time, and 1.2 ounces of the sulfur at a time. It only takes 10-20 seconds for each batch. So to make a 24-ounce batch, you should mill six 3-ounce batches of the potassium nitrate and two 1.2-ounce batches of sulfur.

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 chemical formula for gunpowder is: Potassium Nitrate (Saltpeter): KNO3. Charcoal: C. Sulfur: S. When combined, these ingredients form the chemical compound for gunpowder, which is commonly represented as KNO3 + C + S.

Stir continuously. Add little bits of water at intervals until the potassium nitrate is completely dissolved. 7.

Kurt is very right when he said potassium nitrate is hard on crucible's. Depending on the make up of the crucible, the life can be as short as one use. A while back I tried some silica sand in a flux mix of 50% borax, 40% soda ash and 10% silica sand on copper parts from IC's.

Most people will use a ball mill to both grind up the materials and mix them together. It's a bit safer, and will make a higher quality powder. ... Simply mix the potassium nitrate and charcoal together with a 80/20 ratio. It won't burn as well, but it will still work. Sulfur can also be substituted with iron-oxide (rust).

Potassium nitrate is the most important ingredient in terms of both bulk and function because the combustion process releases oxygen from the potassium nitrate; ... This is achieved using a ball mill with non-sparking grinding apparatus (e.g., …

Ball mill the charcoal and sulphur mix for about 8 hours (without adding any potassium nitrate). While the mill is running; per 100g of charcoal-sulphur mix, place 600ml of isopropylalcohol into a large container and place that in a fridge. In an old pan, take 75 parts of potassium nitrate and add 40ml of water per 100g of potassium nitrate.
