KNO3 was another matter. 4 hours hardly touched it. So I switched to US nickels. In 8 hours the KNO3 was very fine but the nickels had compacted KNO3 on the face and back of the coins so thick that the coins looked like little footballs in profile. What a mess! I then re milled the coins with marbles and salvaged most of the KNO3.
Some decent NC for kno3~~~~~~~~~Check out my latest video: "How To View Invisible Air Currents With Lasers" https://
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 times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

Damp KNO3 in ball mill. I made my own ball mill this weekend, did the Charcoal and sulphur together first but when I added the KNO3 I think it may have been a bit damp (the lid was not sealed) and now the mix is clumping in the ball mill. Would it be possible to add alcohol to the mix to remove the water, dry it and put it back in the ball mill ?
Nitrocellulose film on a light box, showing deterioration, from Library and Archives Canada collection. In 1855, the first manmade plastic, nitrocellulose (branded Parkesine, patented in 1862), was created by Alexander Parkes from cellulose treated with nitric acid and a solvent. In 1868, American inventor John Wesley Hyatt developed a plastic material he named Celluloid, improving on Parkes ...

Page 1 of 2 Question about KNO3/Al flash powder. posted in Pyrotechnics: So I milled up some aluminum that is very fine. It will burn with the touch of a match. However when I try and make any flash powder with it, it will hardy ignite. I have tired ratios of KNO3/Al, 7/3, 50/50, 3/2, and 2/3. 2/3 proved to be the best which is odd considering the fuel is in excess in this ratio. When the ...

Nitration: 1.) Place the potassium nitrate container into the ice bath 2.) Carefully pour 50mL of sulfuric acid into the container of KNO 3 3.) Stir thoroughly for about a minute 4.) Mix in the pulled apart cotton balls one by one 5.) If the mixture becomes too thick, add another 1015mL of sulfuric acid 6.) Once all of the cotton is completely covered, let it sit for at least an hour 7.)

I start with a blade grinder, just KNO3 and a 100 mesh screen. Ball mill is 6" diameter (150x150mm), half full of .690 () musket balls. I tried a drying box over a 60W bulb. No useful effect, more pellets after 4 hours tumble. I tried a drying box with a 150W bulb. No happiness, more pellets after 4 hours tumble. My KNO3 is now yellowbrown.
