You were making stars in a ball mill?

How is that possible?

If you are talking about milling star composition anything other than kno3, s and c, then you have a death wish.
Phew that was close.

hi, i see you've started four threads now, more than ive started in a year!, try and tag your questions on existing threads, like the "star making thread".
i don't know if you have a mill or not? and your simply "hunting for answerers" we cant teach you every step of the way, get a few books on the matter, start with something simple like a fountain,
as for your question , mill chemicals separately, a mortar, pestle would take to long, its all to do with particle mesh size which effects burn rate, the chems usually have to be as fine as talc powder

Question:
I want to start investing in a ball mill, specifically making from scratch, but atm, the parts I am looking for are unavailable so I need a short term solution,
I have seen some really small NatGeo rock tumblers on the internet, will this be OK for a short term solution? And has anyone had any experience with one of these?

I always thought stars were a composition that you had to dissolve w/ solvent then knead, before cutting/pumping. How do you make milled stars??

Using a mill is a reasonable method for preparing the ingredients for star making, almost every pyro has started with a rock tumbler rated as 700g or 1200g approximately.

Hi c.brad, sounds like you were in the middle of milling a star comp, whether it be individual chems or a complete composition and your mill crapped itself..... firstly , if it were individual chems then you will have bigger arms than arnie shwartznegger but it will be possible to grind your chems up there with, separately from any oxidizers ( huge job and not as good ) and then screen them together... secondly, its not a great idea to mill them altogether, concidering we want our stars to take fire very easily on ignition, therefore banging around a loaded comp in a ball mill isn't the smartest idea.. Mill all your stuff up together except the oxidizer, mill that sepparately in a drum that is only used for your oxidizers, then screen them altogether...

Edit :- Ho yea i forgot to say... fix your mill it can;t be that hard
