Do you need a ball mill for black powder? Proportions by weight are 75% potassium nitrate (known as saltpeter or saltpetre), 15% softwood charcoal, and 10% sulfur. These ratios have varied over the centuries and by country, and can be altered somewhat depending on the purpose of the powder.
A device used to reduce the particle size of materials, bodies or glazes. A ball mill is simply a container that is filled with pebbles (either of porcelain or stones Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them.
Black Powder Pucks, Pressed and Crumbled Third Step I take 16 ounces of the dry pine charcoal milldust, add ounce of dextrin (+5%) to it, screen it to thoroughly incorporate it, and coat that BP onto ounces of rice hulls in the star roller (7/1 ratio of BP to rice hulls). I put the coated hulls on screens and into the puffed rice cereal can be used in this process, rice ...

Powder you should add more media until you have a about 50 % of the jar filled. If your mill has problems with the weight, you also can use: Pieces of cut down brass rod. Non sparking stainless steel media (there are some suited types make sure to ask about this before you buy anything) Ceramic media either Alumina or Zyrconia are suited.
As far as placement of your mill, the ideal distance is probably around 150ft or more away from any buildings of any sort. If you can barricade it that's even better (things like sandbags). Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.
In this Mythical Pyro video I show you how to make fast burning black powder. Black powder is the heart of all pyrotechnics, so knowing how to make it is a u...
Spray water into the mixed black powder composition, and work the water into the powder with your hands. Spray one ounce of water (either a fluid ounce by volume or an ounce by weightthey're both the same) into the 8ounce batch of powder. Work it in with your hands.
February 16, 2018 How to Use a Ball Mill Safely and Effectively I have some lump charcoal that just came out of my retort after I cooked it, and I want to turn it into airfloat charcoal. Or, the directions say to ball mill my rocket fuel for an hour. An article tells me to ball mill my star composition prior to pressing my stars.
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.
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?
Posted October 1, 2017. While BP has been made without a ball mill for years, professionally a wheel mill is used, early history was the use of a manual stamp mill, there is now no justification for failing to buy the basic minimum rock tumbler, which is usually available for below £100. A charge of suitable lead or ceramic media ...
I have been working on this idea for some time now. I should be able to demonstrate my screenmixed black powder within a week or two. The intention is to use a 3lb nozzleless rocket to lift a 6" ball shell. The burst will be the same powder. More of the same powder will be used to lift and burst shells.
IMO, magnetite wouldnt burn, since already strongly oxydized, rather it can be an oxydizer (some thermites are made with Fe304 instead of Fe203) but, as mentionned, it is ferrous, can surely transfer static electricity, that's why it's good to avoid this material at all costs in the charcoal, if ball milled as BP afterwards in a ball mill.

lbs, the closer you come to destruction of the motor after a long mill. Get spare belts (4" x 1/8" ORings work) I destroyed three in doing ... With a proper ball mill, fifty pounds of black powder is a weekofevenings task, rather than a "month of Sundays" one.
I've made some pretty good black powder using a coffee grinder and porter porter and pestle, but I was looking into getting a ball was going to get one of the cheap 70 6lb rock tumbler and modify it per skylighter's directions, but I would still need to get media to fill it half full, 200 1/2" balls.
Explosive Manufacturing, Ingredients, Gunpowder: Manufacture of black powder was accomplished originally by hand methods. Ingredients were ground together with a mortar and pestle. The next step was to use crushing devices of wood (wooden stamps), also operated by hand, in wooden or stone bowls. The stamping process was gradually mechanized and, about 1435, the first powder mill driven by ...
Where I live, you can't really buy black powder. I have heard the black powder created by ball milling is superior to that made with red gum. I am planning to buy a 6 lb rock tumbler from HF and modify it a little. I live in a neighborhood, so I don't have that much room to distance the mill from buildings, and want to be safe.
I have never had a, " little mill" but once you get a mill dialed in with the correct media and charge with (dry) chems it doesn't take long to mill powder to it's peak power. some have tested powder every 1/2 hour and found that a correct mill will get it done in 2 hours. That's about what I let mine go. give or take a few.

Gather the cloth strainer to remove the retained solid matter; wring out the resulting "ball" and squeeze it well to remove as much moisture as possible. 14.) Line a baking sheet with newspaper and put in the powder retained in the cloth strainer; break up the ball by hand and distribute the powder well on the paper.
This method will only make slow is my method: Ball mill, soft wood charcoal (willow,balsa,eastern red ceder)are a must. Good potassium nitrate and sulfur. Powders should be ground together with non sparking media for ball mill ie 1/2″ lead balls until powder is like flower.
Existing user? Sign In So my first ball mill is nearing completion, and with everything that I have read, there is a huge variance among fireworks enthusiasts as to how long they mill their powder. I know that this depends on a variety of factors, but how do you tell when your black powder has reached its maximum stren...
Ball mill black powder outdoors. I have made my own mill but I didn't make it until I understood about mills. I learned about them by buying a cheap one and working with it for a while. If you decide to make your own, think about selecting a continuous duty ~1750 rpm motor as the drive (rpm specifications on motors may vary depending on your ...
The stainless steel must be sparkresistant, nonmagnetic steel in the 300series. Alloys 304 and 316 are the most common stainless steels of this type. Highdensity alumina ceramic media is the type I've heard of most often being used in ball mills. Stainless Steel and Ceramic Milling Media
Here are two reasons for using lead balls: Reason #1: They will never spark and cause your ball mill explode. Reason #2: Because of their high density, they will do a much better job of pounding the powder. boredvamper • 10 mo. ago. Not arguing that it's heavier but none of the ones I mentioned will produce a spark.
