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.

WhatsApp: +86 18203695377With 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 ...
WhatsApp: +86 18203695377As 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.

WhatsApp: +86 18203695377Ball 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.

WhatsApp: +86 18203695377Even in a ball mill with lead grinding elements, I would not grind the mixed ingredients.

Why take the risk, when it's just as simple to grind and ballmill the ingredients separately before mixing?
WhatsApp: +86 18203695377Location: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.

WhatsApp: +86 18203695377by J Miller » Mon Oct 01, 2007 3:05 pm. So, and correct me if I'm wrong, black powder does not have enough resistance to heat up and ignite with static electrical sparks. But requires sparks that are from a heat producing source such as primers, flint, or percussion caps to ignite. That seems to be what I'm reading. Joe.
WhatsApp: +86 18203695377Lance 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.
WhatsApp: +86 18203695377The 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.
