A typical gunpowder recipe consists of 75% potassium nitrate, 15% charcoal, and 10% sulfur by weight. Carefully measure and mix the components thoroughly to ensure even distribution. Grinding and Mixing. To achieve a uniform mixture, grind the ingredients together using a mortar and pestle or a ball mill.
One such method is to mill each component separately. Another is to mill the charcoal and sul-fur together or the potassium nitrate and sulsul-fur together. The latter is more hazardous, as one is grinding an oxidizer with another component. However, a worse choice is to mill the sium nitrate and charcoal together.
The potassium nitrate grinds better with the larger 1/2" media. The sweet spot for charcoal in my rudimentary testing was 5/16" diameter. I used rubbermakers …
Below I will list some of these advantages. It is cheaper: Compared to stump grinding and pulling, using saltpeter to remove tree stump can be considered "free".

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. Homemade charcoal can be made for use in gunpowder by grinding traditional hard wood or soft wood charcoal to refine grain material.

The grinding action in a ball mill is achieved through two primary fragmentation mechanisms: attrition and the impact. Impaction happens when the grinding media (balls or hard pebbles) bump into each other and with the material being ground. This leads to the fragmentation of the substance into pieces of smaller size.
Potassium Perchlorate can be set off on it's own, much like potassium chlorate. However, this results in partial detonation, and the force required is orders of magnitude higher than what it would have experienced in that particular ball mill. The answer to all of these inquiries is of course to ball mill remotely.

Black powder consists of three ingredients: Potassium Nitrate (KNO3), Sulfur and Charcoal. The ratio of the mix is 75-15-10 which means 75% potassium nitrate, 15% charcoal and 10% sulfur. The Sulfur and Charcoal provide fuel for the reaction, while the Potassium Nitrate provides Oxygen.
While the CIA method - if properly executed - ensures a superior integration of potassium nitrate, the ball mill method is employed to intimately mix charcoal and sulphur. I personally consider the combined approach to be the best method for amateur black powder manufacture (I attempted to argue why I rate it higher than plain ball milling).

Typically, a small coffee mill can efficiently grind about 3 ounces of the potassium nitrate at a time, and 1.2 ounces of the sulfur at a time. It only takes 10-20 seconds for each batch. So to make a 24-ounce batch, you should mill six 3-ounce batches of the potassium nitrate and two 1.2-ounce batches of sulfur.
