More apt to make the powder stick in a powder measure than ignite it. Been loading for 40+ years and I've never heard of static electricity igniting smokeless powder. While not to be treated carelessly, smokeless powder will not explode. It will BURN vigerously, but only black powder is explosive.

Use the wire tie from a bread bag to hold it in a small roll to put in the range box. When using it at the range use a 6″ nail from the coop or Lowe's / Home Depot and just push it into the ground.". Use Bounce Dryer Sheets — A quick pass with the thin sheets used in dryers will eliminate "static cling" on your plastic reloading ...
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 ...
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.

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.
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.
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.
Ingredients So you want to make gunpowder? Making homemade black powder will require three ingredients. The first is saltpeter ( also known as potassium nitrate,) or ammonium nitrate crystals, ammonium nitrate solution, the second is charcoal (raw, not processed), and the third is sulfur.
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?
Van Der Waals Forces Static Electricity. · When friction is applied in a ball mill, that is literally a recipe for binding two substances together with static electricity. But something else also happens to the fumed silica inside the ball mill: The fragile strands of nanospheres are crushed and broken into tiny pieces.
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal ), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.
6 Lb Rotary Ball Mill Kit. 1 6 Lb. Rotary Ball Mill. 6 Lb capacity DOUBLE Barrel ball mill. Perfect size for milling 2 different comps at once in separate drums.

To make 500gram batch Dissolve 375 grams of the prilled Potassium nitrate in 300ML of water the powder will dissolve as the pot is heated. When the liquid in the pot turns clearno white crystals add 125 grams of the milled sulfur/ (willow)charcoal. It takes a lot of mixing to get the fluffy powder mixed in.
Static Electricity and Black Powder « on: August 22, 2020, 01:44:22 AM » In Dennis' post concerning storing black he mentions static electricity. That seems to be a topic that gets batted around occasionally on various forums. Back in the day, I believe I remember one on the old MLML and TOF had some good insight on the subject.

With black powder and its high amount of carbon, a static charge will travel around the outside of the powder grains meeting little resistance so it produces almost no heat. If the static charge did have a significant amount of amperage (which is doesn't), the low resistance caused by the presence of the carbon in the powder would not cause the ...

black powder ball mill static electricity. Ball Mill Static Problem . · Ball Mill Static Problem posted in Newbie Questions I am currently constructing a ball mill and I noticed a potential safety issue. My design has a pvc drum sitting on top of 4 small caster wheels. The drum will have a belt around it which would be turned by a motor.
The US Bureau of Mines admits that static electricity can ignite black powder and they have proved it with experiments. See post #4 >>> Static Electricity "The United States Bureau of Mines reports that confined powder can be ignited by electrostatic discharge energy of J, whereas J are required for unconfined powder. Dahn and Reyes ...
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.
