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.
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.
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 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 ...
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.

8 Static electricity and black powder I have read that a powder dispenser for black powder should not have a plastic hopper. Something like a Lyman 55 classic with an aluminum hopper is needed because of the risk of static electricity causing a spark. However, black powder is now packaged in a plastic container.
Measure out your beans as normal. (This technique works better if it's a singlebrew's load of coffee beans, vs a full roughly 8oz hopper.) Wet a spoon handle. No need to be a big or fancy spoon. The spoon James uses is smaller than a teaspoon. Stir your measured beans with the justwet spoon handle.

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.
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.
The standard method of charging on powder processing operations is due to triboelectrification, which is basically the contact and separation of the powder with processing equipment, the powder itself, or other factors that can cause charging, like surface contaminants. There are numerous types of equipment that can cause the charging of powders.
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.
The ventilation effect of the ball mill is roughly in two aspects: one is to discharge the fine powder in the mill in time, so as not to affect the grinding efficiency; second, to reduce the temperature in the mill to avoid the grate of the gypsum dewatering tail bin paste ball.
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.".

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?
Electrically Conductive Greases Nye Lubricants General discussion of static electricity effects . The tube mill is similar to the ball mill in construction and operation, although the ratio of length to the diameter is usually 3 or 4:1, as compared with 1 or :1 for the ball mill.
