Pyromaniac Full Member 79 posts Posted 20 June 2017 10:47 AM As far as I know, grinding mixed chemicals in a coffee grinder is extremely dangerous. Mortar and pestle might, work don't take my word for it though. Ball mill is the "safest" way to mill it to my knowledge.

Run the gunpowder ball through a kitchen sieve to break it into small pieces, then let the pieces dry out on a piece of paper. Again, be extremely careful around the gunpowder. Exercise caution at every stage. 5. Store the black powder safely. [8] Place the black powder in a special container designed for gunpowder.

What is a ball mill used for? Ball mills are commonly used for crushing and grinding the materials into an extremely fine form. The ball mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it.

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.

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.

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 ...

Ultimate particle size depends entirely on how hard the material you're grinding is, and how long the Ball Mill is run.

Another similar mill is the Rebel 17, which is supposed to be a heavy duty version of the Model B. It has stronger rollers, powder coated jar, and stronger bearings. They're usually around 30 more expensive than a stock model B. The black jar wouldn't hurt to hide charcoal stains either.

As far as placement of your mill, the ideal distance is probably around 150ft or more away from any buildings of any sort. If you can barricade it that's even better (things like sandbags). Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.

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).

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.

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.

Depending on who and where you ask, the "optimal" ballmilling varies from 4 hours to a full day. I would like to gather some experience from you: How many hours do you ballmill your BP, and for what purpose? And, propably the most important question: Can you mill for too long, and ruin the result? Blowing shit up is not a goal in itself.

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.

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.

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.

Pyrotechnics. ball milling black powder. hondo. ActionTekJackson. Simoski. Arthur. ×. I have been ball milling my bp for a year now, and lately my powder is clumping up in the mill, it use to come out nice and fluffy. Whats happening, is the potassium nitrate or sulfur absorbing moisture and causing the clumping problem.

Ball Mill from Skylighter (#TL5005) It is the ballmilling which will give our powder the power we need. Ballmilling the black powder ingredients ensures a very small, fine particle size. This maximizes the surface area of the ingredients, and the resulting burn speed. After milling, the ingredients are also extremely intimately mixed.
