Hi all!

i recently built my BallMill.

i've just finished milling my first batch.
i milled 3kg batch for 30mins. then as i understood 3kg was toomuch for the jar, i reduced it to about 2,3kg that seems the quantity i can see the last ball media surface.

well i milled this 2,3kg for more 2,5 hours so now i've milled that batch for about 3+ hour.

now i want to know how i can know if my powder is milled enough.

i made some test:

1) burned as it is.
2) burned after granulated with about 2% dextrin

1) give me the same result of coffee grinded powder (test made some week ago in a *safe way*!)... but this is what i can say from what i've seen... i can't really say if it is 10% better or worst...
2) give me the result that 0,7g of granules seems to burn in a 'woosh' (so quicker than 1) ) ... but my impression is that it is not comparable with lift charge i find under commercial aerial shell... if i burn 0,7g of this last, it burn in a greater woosh and quicker (i can't say if much quicker or few quicker)

a thing is sure, the powder i have now is the finest i have nerver seen... it pack it self with very easy... in a plastic container , two tap tap on the wall are enough to create deep cracks and canyons in the powder...
i think that i will not obtain a finest powder milling it further. i want to make present that, before milling BP, i milled chems separately to airfloat grade.

so now the question is: how can i 'measure' my powder?
do your granulated powder have the same explosive power of commercial shell's lift charge?

how could i improve my bp if you also think my powder quality is not so good?

thanks
