How to Ball Mill Chemicals Safely — Skylighter, Inc.

In making black powder, I've found that a material charge of 15 ounces of potassium nitrate, 3 ounces of airfloat charcoal, and 2 ounces of sulfur produces the most efficient quantity of BP mill dust. The density of the mill dust, and therefore the volume it occupies, will vary a bit with the density of the charcoal used.

They have a very high specific density (1200kg/m3) and bulk density (800kg/m3) compared to 60 to 180 kg/m3 of loose biomass. Hence, they offer a more concentrated form of energy than firewood or charcoal. Slow-burning: The compression procedure allows the briquettes to burn for a lot longer than if it was loose in its original condition.

Charcoal - Wikipedia

Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of …
