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.

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.
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.
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. ... In the case of ball mills, used for the purpose of producing Black Powder, the ball mill rotating drum chamber, is filled 1/2 full, with lead ...
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.
by 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.
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.

Posted 13 January 2015 01:39 PM. Hello guys this is my first tutorial in this hope you like it any criticism is accepted. First a few wards about ball mill is one of the most important tools in the pyro is used for grinding course chemicals into fine powders and making black mills can be bought or custom ...
In this video, I start by showing that homemade black powder doesn't burn very well if the ingredients are only ground separately with a coffee grinder. Then...
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.

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.
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

There is paranoia when it comes to handling black powder, what would happen if there were a remote chance that you would get a static electricity spark from the plastic bag? the powder in the bag would just burn up. But I doubt very much if that could ever be the case. ... Midway USA Round Ball. Loyalist Dave; Jul 7, 2017; Vendors and ...
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.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

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.
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.
Hodgdon Powder Inc. has announced that, effective immediately, it will cease all manufacturing at their Camp Minden, Louisiana plant. For those of you few decent, God fearing Americans left among us, you know that plant as the facility currently manufacturing the GOEX and Olde Eynsford brands of black powder. From the Hodgdon Press release ...

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 ...
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 ...
It is worth checking hardtoreach areas for stray or loose wires. Static electricity can also build on combines and create a small spark when discharged. Some earlier studies suggested that static electricity can start combine fires, and drag chains or other devices should be used.
