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.

Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal ), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.

The longer the ball mill runs, the stronger the black powder will be. A general rule of thumb for all pyrotechnic mixtures is "the finer the powder is, the faster it will burn." ... Flash powder in an M80 will make a loud explosion and fragment the tube into small pieces. Flash powder burns so much faster than black powder that in larger ...

To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour. Your nitrate should be light and fluffy. If not, continue grinding it 'til it's fine powder with no chunks or grains.

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 ...

In my own experiments, I've found that I had to press the powder into "pucks" and crush and screen to get near the performance level as Goex. The economics of the home made black powder is very attractive if you don't count labor or equipment investment. The bought potassium nitrate and sulfur add up to about 3/lb.

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.

It influences the final particle size and the quality of the black powder. Longer grinding durations and fasterrotating speeds produce finer powder. Overgrinding the combination might result in undesirable effects or risks. Safety Considerations. It is critical to take necessary safety precautions when using a ball mill to make black powder.
