Extremely hard, lead ball media for ball milling black powder and individual chemicals. If you are making black powder, you have to use nonsparking grinding media. Lead is nonsparking and is probably the safest thing to use for making BP. Pure lead balls are very soft and will literally grind themselves down to nothing.

I used to use a coffee grinder however the last time I milled some I resorted to a mortar and pestle instead, which was far too much work. I know ball milling is the most common...
He said he had a big explosion ball milling black powder using ceramic media. Thought I’d pass along the info†Thanks, Cal. What you want is lead or brass grinding media. Lead grinding media can be had from all sorts of sources. For small mills, you can use the .50 caliber round balls obtainable at black powder gun shops.
The ideal milling method for optimized black powder milling involves what is called "cascading" action. This is a continuous flow of media file: ... Figure 2 shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a ...
The Media The ball mill consists of the mill base and the mill jar. There's one more important component to a ball mill, though: the media. The balls of heavy material which fall upon and crush the chemicals are called the milling media. ...

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.
Run the gunpowder ball through a kitchen sieve to break it into small pieces, then let the pieces dry out on a piece of paper. Again, be extremely careful around the gunpowder. Exercise caution at every stage. 5. Store the black powder safely. [8] Place the black powder in a special container designed for gunpowder.

Black powder MUST be made in a ball mill to work properly. A ball mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours. As the ball mill rotates, the lead balls will crush the chemicals together ...
Mix for 4 hours in the ballmill with brass media; 2. 75% potassium nitrate. 20% sulfur. Mix for 4 hours in the ballmill with brass media; 3. Mix the two compounds in the ballmill WITHOUT the brass media for an hour. Of course between the first and the second step the barrell and the medias must be carefully cleaned!
My very first ball mill such as it was used a few pounds of stainless steel nuts and bolts for the medium charge. Ball bearings are very good for milling. Muzzle loading balls are, also. Fishing weights work (egg weights are about the best). Marbles work. Some people (scaring me as they do it) use glass marbles to mill black powder. LLoyd
The potassium nitrate is a bit tougher to mill completely in such a small jar. If the media is larger than 3/8", the efficiency drops off. I only mill the nitrate for 2 hours though. So, with 8 hours of total milling time (with no risk of explosion), you can produce 300 grams of excellent black powder better powder than if you milled it all ...
The grinding media (balls) are often made of leadantimony alloy, or tungsten carbide. Steel is usually avoided, since it will spark. There are several types of ball mill: ... while in the case of black powder a singe spark can cause detonation of the powder. Ball mills in general are not used for grinding black powder, powder mills are instead ...
Now, let me be clear. I consistently recommend to anyone making fireworks today that they get a ball mill, and learn to make black powder using it. Period. It is an absolutely necessary tool for every serious fireworker. ... You don't have to invest in a ball mill and the increasingly expensive grinding media for itusually hardened lead balls ...
thanks Randy on March 24, 2013 at 1:34 PM Good article Harry, Now you should investigate the alternative way to make superior Black Powder. Those prilled Potassium Nitrate crystals will dissolve in heated water and so there's no need to premill.
