1.9k. Posted April 23, 2010. One of the very first major acquisitions any pyro makes, beyond the necessary chems, fuse, and tubes, is a decent ball mill. You can buy a rock tumbler, and it will work, but a much better option is to make your own. When I first joined , I did a blog on a basic ball mill that was designed to go together in ...
As far as ball mill safety goes, the motor should be completely separated from the milling area, so that no powder can get to the motor. I also barricade my ball mill with a thick inner layer of Styro surrounded by an outer layer of concrete blocks. The least you can do is prepare for a potential accident.
August 29, 2016. 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 well-known friction-increasing additive. And either way it's too hard, increasing the risk of impact ignition.

March 26, 2007. Pwdering magnesium or aluminum by ball mill is a real pain, but 50/50 magnalium alloy can be powdered with ease as it is extremely brittle and crumbles in rather mild conditions. Smaller batches can be ground to size by a mortar and pestle. 3 years later... September 17, 2010.

Anyway it's a triple jar ball mill, each jar is about 1.3liters in volume so at full capacity it should churn out 600-700grams of high quality BP in a couple of hours. The motor was salvaged from a lathe and it has 400W power which is more than enough to rotate the three jars at 100RPM
1. Only mill KNO3. Never use a more powerful oxidising agent. 2. Never mill colour comps. 3. Make sure you use LEAD or other non-sparking media. 4. Ensure the mill is away from the house - a garage may be best (without car!) 5. Dampen the mixture - ensure that it's damp at all times - approx. 8% water. This would mean that for 100g of

Somewhere around here I reported my results with various sizes of SS media from 3/16-1/2" diameter spheres, using a 4" diameter mill jar to mill the charcoal. The potassium nitrate grinds better with the larger 1/2" media. The sweet spot for charcoal in my rudimentary testing was 5/16" diameter.
There are a few critical decisions you have to make before building a ball mill for pyro use. Obviously, a ball mill requires a jar or jars & enough grinding media to fill one or several 50%. Jar size dictates the amount of grinding media you will need. Grinding media often costs as much as the mill (sometimes more).
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.
