— Standard length mill times are half an hour for individual chemicals, and 2-4 hours for high-quality black powder. 6-Pound, Dual Drum Ball Mill (Skylighter #TL5005) Note: Some companies also sell similar, but less expensive 3-pound, single-drum mills. But they will not handle the weight that we will be loading into the jar.

— This method will only make slow powder.This 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.
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 …
— 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 mill.I 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.
— It never goes bad, even if it's gotten wet or has been stored for years. So learning to grind/mill hard chemicals is one of the routine tasks that all fireworkers need to master. We routinely recommend two ways: …

— The small mills require extra milling time to make good powder. That extra milling time is a safety concern if milling live powder in an area that has people nearby. When milling the components singly, the mills can be left overnight or throughout the day without fear of accidental ignition.
— Hi, I have been reading many posts and other references in preparation of making my first batch of black powder including accident reports. I have a 15 lb capacity rubber lined rock tumbler (Thumbler's Tumblers) and 200 brass 1/2" beads. If I am making standard black powder with this setup what i...

— The ratios: This is the most important factor for ball milling success. Your mill jar should be 1/2 full of milling media, and ¼ filled with chemical(s), with ¼ of the mill jar left empty. Here's an easy way to get it right: first fill an empty mill jar one-quarter full of your chemical(s). With this mill jar, approximately 4.4 ounces (125 ...
— Mendonça et al. investigated the influence of milling duration, ball-to-powder ratio (20:1), and milling rotational speed on the production of recycled stainless steel powder from machining chips. They employed a complete factorial design technique to optimize the ball mill conditions and found that these specific parameters led to a small ...
— Does anybody here think that milling the aluminum foil with glass marbles is going to cause an explosion? It seems like maybe everybody is unconsciously adding 'black powder' to the words 'milling with glass marbles'. The Youtuber isn't milling black powder, nor is he going to use his aluminum in anything that gets milled again.

— The ball mill process parameters discussed in this study are ball to powder weight ratio, ball mill working capacity and ball mill speed. As Taguchi array, also known as orthogonal array design, adds a new dimension to conventional experimental design, therefore, Orthogonal array (L9) was carefully chosen for experimental design to …
The rule of thumb is if you can grind the material into a powder using a mortar & pestle, a Ball Mill will most likely work for the purpose. Ball Mills work by employing various types of media (either steel, ceramic or lead balls) to crush the material in the barrel. To use the Mill, the material to be ground is loaded into the barrel which ...
Our ball mill grinding products apply the ancient principle of ball grinding to the industrial needs of the modern world. Many different industries can benefit from the grinding action that these mills offer: they are suitable for both dry and wet grinding as well as cryogenic grinding, and are commonly used for mixing or grinding chemicals, ores, paints and …
During the high-energy ball milling process, the powder particles are subjected to high energetic impact. Microstructurally, the mechanical alloying process can be divided into four stages: (a) initial stage, (b) intermediate stage, (c) final stage, and (d) completion stage. (a) At the initial stage of ball milling, the powder particles are ...

The use of ball milling as a defibrillation method after a series of pre-treatments of raw materials was also described by the group of Elkoun, who reported the extraction of CNFs and CNCs from carrot pulp by ball milling and acid hydrolysis respectively. 60 More in detail, NFCs were obtained from never dried carrot pulp (4%) by ball milling ...
A planetary ball mill, for example, offers a big jar volume compared to a mixer mill and shows a high value on this diagonal. A mixer mill in contrast offers various possibilities for temperature control and has a high value in this field. Considering that a single ball mill is most often used for a variety of applications, a good compromise ...
— This article is informative and a good place to start. I haven't tried it - yet. I have done the CIA method (alcohol precipitated BP) and it produces powder worthy of respect. I did a small batch (500g) as a test of the method, and found it to be useful powder, infinitely better than green/mortar+pestle stuff, but not close to ball milling.
