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

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.
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.

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.
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.

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.
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.
