Dragonflightpyro Posted August 22, 2015 Posted August 22, 2015 So I tried a batch with the dried KNO3 and Charcoal. I got the same thing, fully clumped at the end of the barrel with the grinding media just rolling against it. I can see where the balls made a groove in the clumped powder so I don't believe there is much grinding taking place at all. I'm now trying to figure out means to dry sulfur. I was told it has a melting point close to the boiling point of water. Can I oven dry it at low temperature? Would that make my house literally smell like hell? How much drying out do desiccant packets actually do? If I just keep a few in a gallon bag of S, will it dry it out or just prevent further hygroscopic activity? Thanks for any help. -Alex P.S. As far as temperature goes, it is slightly warm out, but it is shaded and I have a large fan blowing on my ball mill; it isn't even warm after hours of continuous running, outside or inside.
Ubehage Posted August 22, 2015 Posted August 22, 2015 When I opened my milling box everything was hot inside from sitting under the sun. I believe that in combination with a little moisture caused this.I would be careful placing a black (or even any dark-colored) ballmill in the sun.In worst-case scenario, it might accumulate enough heat to make a reaction more liable to happen.
Dragonflightpyro Posted August 24, 2015 Posted August 24, 2015 An update on my BP milling: I recrystallized my sulfur, ground it to fine powder (I don't know what size exactly but passed 200 mesh) and made another batch. No clumping at all. My problem was apparently all my chemicals were "wet." Thank you so much to everyone who helped! 1
