Do it on a day that's not too windy. Spray water into the mixed black powder composition, and work the water into the powder with your hands. Spray one ounce of water (either a fluid ounce by volume or an ounce by weightthey're both the same) into the 8ounce batch of powder. Work it in with your hands.
Where I live, you can't really buy black powder. I have heard the black powder created by ball milling is superior to that made with red gum. I am planning to buy a 6 lb rock tumbler from HF and modify it a little. I live in a neighborhood, so I don't have that much room to distance the mill from buildings, and want to be safe.

Powerful black powder can be made with mill runs of between 2 and 4 hours. Use long drop cords. Unplug the cords at the electrical source, not at the ball mill, when you want to stop the mill. Run your mill remotely, outdoors, at least 150 feet away from people and inhabited buildings.

Process. While there are a few ways to approach the recipe, a good gunpowder mix should end up looking like the following ratio: 75% potassium nitrate / salt peter, 15% charcoal, and 10% sulfur. Whether you are dealing with a batch size of one pound or one hundred, the ratio stays the same.
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.
Mix for 4 hours in the ballmill with brass media; 2. 75% potassium nitrate. 20% sulfur. Mix for 4 hours in the ballmill with brass media; 3. Mix the two compounds in the ballmill WITHOUT the brass media for an hour. Of course between the first and the second step the barrell and the medias must be carefully cleaned!
wheel mills to crush sulphur when he began in 1802, but did not use the mill to incorporate the ingredients until 1822. Even though du Pont has been the subject of recent debunking efforts, as a powder maker he was the best in the country. The roll mill, or wheel mill, did not change much. All sources consulted so far indicate that it was
Posted October 1, 2017. While BP has been made without a ball mill for years, professionally a wheel mill is used, early history was the use of a manual stamp mill, there is now no justification for failing to buy the basic minimum rock tumbler, which is usually available for below £100. A charge of suitable lead or ceramic media ...
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.

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 ...
Posted 28 August 2016 05:37 PM. It's hard to prove that glass sparks, except finding a reference to it's piezoelectric properties. But that's only part of the problem. Glass is brittle and will flake off, and ground glass is a wellknown frictionincreasing additive. And either way it's too hard, increasing the risk of impact ignition.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

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.

How to optimize a 6 pound ball mill to safely and effectively ball mill homemade black powder. Here's Your Next Ball Mill What is a ball mill? ... Powerful black powder can be made with mill runs of between 2 and 4 hours. Use long drop cords. Unplug the cords at the electrical source, not at the ball mill, when you want to stop the mill.
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 ...

Mill all three components together to integrate well. The actual milling time depends on the efficiency of the particular mill. 23 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.
It is usually made by milling charcoal, sulfur and potassium nitrate together. The length of time it takes to mill black powder depends on the size of the mill and the desired fineness of the powder. Generally, it takes between 12 hours to mill black powder to a fine consistency.
Ball mill black powder outdoors. I have made my own mill but I didn't make it until I understood about mills. I learned about them by buying a cheap one and working with it for a while.

But yes your powder is good. BTW. there are some european supplier that also sell the shells by the mm size where they just print n" × 25 mm as nominal diameter (they still are the same and a 4"shell doesn't fit inside a real 100 mm mortar but in a 102 mm).

Having done black powder in a homemade cylindrical ball mill made of pvc pipe, and milling for hours at a time. I've had no issues using ceramic media. If you have it running the right speed, it will grind. It shouldn't be running so fast as to run up the side of the wall and drop from a height. Fluidized bed effect is what you're shooting for.
