I am well aware of the vast number of hazards involved in the making of black powder. Ranging from, but not limited to, heat, open flames, static electricity even percussion. I will not be doing this in large quantities. A 1/4 of a pound to begin with would be a good starting point. I realize powder mills of the past had a very high accident rate.

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.

Lance Sergeant. Apr 28, 2010 #2. I believe the problem is the static electricity is created by black powder dust and grains colliding in mid air as they fall down the tube. Brass or copper tubing would probably absorb the generated electricity much more readily that most other metals and discharge it to the gun barrel.

Ball mills may build up static charge, more so if the drum is made of plastic. This makes grinding flammable or pyrotechnic materials, such as metal powders, organic powders or black powder, extremely dangerous as airpowder mixtures are explosive, while in the case of black powder a singe spark can cause detonation of the powder.

The answer comes from the fact that black powder, and other carboncontaining propellants, are fair conductors of electricity. When a material conducts well, it takes a lot more current to heat it up. This is why the lamp wire stays cool and the filament in your light bulb gets white hot.

Location:Manitoba, Canada Posted November 2, 2008 If you plan on being a pyro long, plan on using lots of antistatic spray. To prevent the mill from being a triboelectric generator, use metal rollers (preferably ground them and the motor as well). I had a little mill for a while that operated like yours, it works but you'll outgrow it quickly.

Static setting off black powder is an old wives tale that has been completely disproved. There is a video out there with a ton of experiments trying to get black powder to ignite using static and piezoelectric spark. I think the end supposition was that the graphite coating on the BP sends the electrical current around the grain, not through it.
