shockie Posted December 1, 2020 Posted December 1, 2020 I was just wondering if anybody had any experience Ball Milling KP.....Is this a bad idea? Any replies will be appreciated.
MinamotoKobayashi Posted December 1, 2020 Posted December 1, 2020 Yes, it is really a bad idea ... never mill anything contains chlorates or perchlorates !!!But You can still ballmill KP soaked in ethyl alcohol.Please refer to an old tutorial of mine here: https://www.amateurpyro.com/forums/topic/13068-how-to-make-very-fast-kp/
justvisiting Posted December 1, 2020 Posted December 1, 2020 I think we are having the same confusion as before. To many of us, KP is the abbreviation for potassium perchlorate. For others, KP is the abbreviation for perchlorate-based powder. The OP seemed to stress that he meant potassium perchlorate only. In that case, no problem 1
shockie Posted December 1, 2020 Author Posted December 1, 2020 (edited) Ok I got 1 person saying no and one saying no problem. And yes I meant KCIO4, Potassium Perchlorate NOT Potassium Chlorate . And I'm talking about BM/Grinding KCIO4 by itself......NOT with any other ingredients. If Ball Milling is a bad idea, what about using a coffee grinder? .... I've seen KCIO4 on several websites varying from -200 to 325 mesh.....I would like to get it down to a quarter of either of those. And what's the difference between Potassium Perchlorate and HIGH Purity Potassium Perchlorate? Do either have anti-cake in them? Yes, my wording can be problematic as I have 1 foot in the pyro world and 1 foot in the rocketry world. If one was to look at a Venn diagram , I'm in that small overlap area. :-) Edited December 1, 2020 by shockie
justvisiting Posted December 1, 2020 Posted December 1, 2020 Hmm. I don't know who wrote that stuff in the post above this one, but I don't think it was me! If it was, I'm really losing it I think I would have been the "one saying no problem" to whoever made that post.
Arthur Posted December 1, 2020 Posted December 1, 2020 Potassium perchlorate is simply a crystaline powder and can be milled down to the mesh cut required. Beware that milling makes fines and these may be no use - don't mill too much or too long.
MinamotoKobayashi Posted December 2, 2020 Posted December 2, 2020 (edited) Ok, if You mean potassium perchlorate powder it is ok to ballmill it also in dry form.But usually KCLO4 is sold like talcum powder and do not need to be ballmilled like KNO3, that usually is sold with sugar-sized grains.I suggest You do not use lead balls because they can contaminate the perch easily and the resulting powder will be grey-ish.Usually I use brass balls, but they are much expensive, so You can also use stainless steels balls without any kind of issues.
