Now, I want to talk about why this produces such high quality black powder. Black powder is a oxidizer/fuel mixture. The charcoal is the fuel and the potassium nitrate is the oxidizer. The efficiency of the powder depends on how well the burning charcoal can get the oxygen from the potassium nitrate. Two things will improve this.

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.

Mill all three components together to integrate well. The actual milling time depends on the efficiency of the particular mill. 2-3 hours should be considered the minimum with typical amateur ball mills. Some choose to ball mill the Sulfur and Charcoal together separately from the Potassium Nitrate for a large part of the mill time.

The grinding process was not improved upon until modern ball mills came along in the last century. Particle size with ball mills can be even smaller and more uniform than with the huge grindstones of yesteryear.
