The Shooting Times staff have received questions lately about static electricity and reloading safety. The questions tend to have two parts: Is it dangerous in a reloading setting and how to deal with it. "Static" means "not moving." Static electricity consists of stationary charges that build up on one surface, creating an imbalance of charged ...

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.

Static electricity has caused a lot more than given credit for. I also had to work with disbursing and design of facilities for storage and handling flammable and combustible liquids and solids, along with other chemicals (to store them separately and safely). The simple fact is that a liquid (or powder) being mixed or poured will build up a ...
Even in a ball mill with lead grinding elements, I would not grind the mixed ingredients. You have a large amount of powder, in a confined space, in a glass container (hmmm, shrapnel!). It's a disaster waiting to happen. Why take the risk, when it's just as simple to grind and ballmill the ingredients separately before mixing?

The ball mill grinding is a complex process with many influencing factors, and these influencing factors restrict and affect each other. The grinding efficiency of the ball mill is determined by the rotation speed of the ball mill, the grinding media (material, size, static filling rate, etc.), the materialtoball volume ratio

Experts tell us not to put BP in plastic containers and to replace the plastic hoppers on our powder measures with expensive brass ones then they ...
2. Flow problems created by static electricity The triboelectrification of the bulk solids can lead to different problems, especially : A bad flow of powder out of hoppers or a powder build up A segregation of the bulk powder will separation of large and fine particles A change in the bulk density of the powder
As MarxMunitions recommends, after the hopper is emptied, wipe down the inside with a drier sheet. Do this routinely and static should not be an issue. Static can cause powder "bridging", which can block the powder flow and cause light loads and squib loads. Reply Quote.

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.
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 ...
Ball milling your black powder is the only way I know of to make the powder fine enough to nicely coat the rice hulls, and powerful enough to make good burst charge. Skylighter's TL5005 ball mill will make ounces of BP/binder at a time, and Skylighter's TL5010, one gallon ball mill will handle a 21ounce batch.

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.
