Someone on the list (Rod?) suggested to me that I ball mill the granite I'm
going to experiment with. So, I googled ball mill and among other things I
found this:

Yeah! Someone else talking about building stuff. Yahoo. Oh wait a
minute.....black powder........BOOM!
I've come across this website and design and wondered if it would do enough
grinding for use in ball milling glazes or even terra sig. It is really
for grinding boom boom for handloaders (the pyroes).
Because the grinding would only be between the grinding media and not also
against the jar sides, the design doesn't seem great for potter's
purposes. It might work anyway, but I'm holding out for someone to give me
some porcelaneous stoneware and offer to fire my ball mill jars. The rest
is a piece of cake.

Hi Linda,
This is a very cool Site...
The Ball Mill which is the Home-Made version, I think would benifit for
having the Motor situated underneath.
The design of course could also be adapted generally for one or more quart
size
Plastic or other Jars useing a much smaller Motor, and one or more
additional,
more closely spaced rubber-rollers, for those who may only
need to mill small quantities.
Overall...seems like a cool Company whose Manufatured Ball Mills appear
straightforward, sensible and reasonably priced. Refreshing to see...
Thanks for posting the Link...

Linda, great and easy to follow plans. The one thing to be careful about
is the use of lead balls. I would suggest not using lead balls. Just go
ahead and get some marbles or porcelain balls. This will avoid the
associate health risks and glaze contamination that would occur if lead
balls are used.

If you are grinding against the jar sides then:
1. Your jar is not full enough and/or
2. your speed is wrong
Plastic jars work well but have a limited life. I use gallon olive jars
sometimes.
If you are going to ball mill the granite it might help to heat it
quickly to above quartz inversion hold it there and cool it fast as
well.

Hey Louis,
Often the case, but if I'm going to be ball milling rock glazes for 12
hours, I'm going to make darn sure I get every bit of grinding work out of
my set up and that includes the front end of a properly milling cascade. I
also don't want to be using up all my cool plastic bottles as Nalgene
bottles or polyprop. carboys are expensive. Anyway making your own ball
mill jars is my next assignment before David Hendley allows me to make my
own cell phone and then lightsaber.
Of course I don't have a mill yet and I can't seem to find any rocks around
to mill but I'm looking!

Taylor, others considering building a ball mill,
Side-by-side grinding tests of ball milling fine alumina in plastic jars versus ball milling same in porcelain jars indicate all significant grinding occurred in the porcelain jars. The plastic is apparently too resilient and just soaks up the impact force. It's kind of like trying to break rocks on a mattress by hitting the rocks with a hammer. :-(
Ball milling in plastic jars, while not doing much grinding, does break up lumps, which is a HUGE benefit with fine clays and colorants that you want perfectly dispersed through a glaze. In fact, ball milling a slurry in a plastic container is often used where the goal is to disperse the contents without grinding them.
Dispersion milling will also not contaminate the glaze because little abrasion of the balls occurs. Actual grinding in a porcelain mill, however, does wear away the balls slowly and changes the glaze slightly by putting ground porcelain into it, which is usually not a problem, just a fact.
Good potting!

What does my reusable jars in is wear between the rack and the jar. I
built a nice jar once out of plastic drain pipe once, wish I still had
it. I have a nice section of drain pipe and am waiting for plastic for
end caps to appear.. I have some porcelain jars, although I lost one
recently. Wore thin.

Aluminum oxide from a previous post does not get ground by porcelain.
Its harder than the porcelain. It may get pulverized.

Change your supplier.
The 1 gal plastic jars I get from a lapidary equipment supplier cost
A$15 & are used to grind SiC grit & agate for weeks on end, what matters
the piddling time potters use for glaze grinds, even my celadon grinds
at 6 hours per batch.
