I generally use the traditional ratio of 75 parts potassium nitrate, 15 parts charcoal and 10 parts sulfur. If your black powder is intended primarily for use as lift powder, you might want to use the ratio which is purported to be optimized for this purpose. It is 74 parts potassium nitrate, 14 parts charcoal and 12 parts sulfur.

You can always rewet the powder and regranulate it. Many people use water to wet the powder for granulation. I use pure alcohol. It will dry in a matter of hours. Water can take three of four days to dry enough to use. The 5/8''s full is to give room for the balls to do their cascade, your better at 1/2 full.

But in a ball mill the relatively gentle tumbling action of mixed black powder chemicals and lead balls is far less dangerous. So, while a blade mill is great for quickly milling one chemical, it is extremely dangerous to use for mixed chemicals. Here is a short article on how to mill powder using a coffee grinder.

Ball mills used to produce explosive mixtures such as black powder should never be operated inside buildings inhabited by people. They require a separate facility away from buildings and flammable substances and protected from the public with a suitable defence wall or barricade made of something with some mass to absorb possible fragments from the exploding ball mill.

I followed Ned''s article on Skylighter when I ball mill, but being a noob, not sure if I should stick to this process or not. I use 6" PVC jars filled with a 20oz charge, mill for one hour, then use it for burst, lift, etc. So far, only milling for one hour works fine for lifting my 4" shells(i use 1.75oz) as well as coating the rice hulls for

Have not made black powder since I was, oh, 12. I have a Harbor Freight tumbler with its two rubber chambers suitable for milling BP. (I don''t use the small rubber chambers for brass cleaning as I built a larger chamber from 4" PVC that holds more and is easier to seal and open.) Some say "ball mill the BP ingredients using lead balls."

My milling media consisted of about 30 .50 Cal rifle balls, and the charge of black power was only about 3-oz.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
