All10Fingers Posted Sunday at 12:16 AM Posted Sunday at 12:16 AM This has probably been discussed here previously but I didn't turn up any answers in my browsing around. My ball mill ate the dust over this winter and I find myself unable to make fast BP. I've made a few batches with screening and wet mixing, but it's only...meh quality compared to the milled stuff. I've been reading here and it seems many of the more experienced people are using kp. I've never made it before but I might give it a shot. My question is, does kp need to be milled like bp? Or is a thorough screening and/or bag mixing adequate for desired performance? Side note...I do have a vibratory rock polisher laying around. Might that substitute for a rotating style mill?
Carbon796 Posted Sunday at 03:19 AM Posted Sunday at 03:19 AM (edited) If you're talking about using it for burst. In your machine wound core " shells ". They will just be more of a salute type effect, than they already are. If you're talking about using it as lift. If you put a heavy enough shell on top of it. You'll have a salute mortar. If you're talking about using it for burst in ball shells. Enjoy. Yes, it's just screen mixed. Usually coated on to rice hulls. Edited Sunday at 03:19 AM by Carbon796

Remember only BP made of potassium nitrate, Sulphur and charcoal is ball milled with all safety measures and remote operation ,besides it can be used to mill individual chemicals into fine powder with cleaning of media and jar neatly every time. You MUST NOT mill kp based BP or any composition except bp in ball mill. You should screen mix KP and fuel. It is being used as a burst charge and should be coated over rice hulls/cotton seeds etc. No any information regarding to be used as a lift charge.
