Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Potassium nitrate is an inorganic salt with a chemical formula of KNO3. It is a natural source of nitrate and has been used as a constituent for several different purposes, including food preservatives, fertilizers, tree stump removal, rocket propellants, and fireworks. Potassium nitrate is a common active ingredient in toothpaste, exerting an antisensitivity action.

Then I put in my granular KNO3, powdered S, and Charcoal. Fill one rubber jar with 2kgs of lead 1/2 media, then 150g of KNO3, 20g of S, and 30g of Charcoal. I let that mill for 810 hours. Separate the media out from the mix and start again. It will help alot if you put a bit of light oil onto the bushings on the Ball mill.

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 ?
