Hello - I need a way to grind silver bullion into basically dust sized
particles. I have manually taken a rasps, files and such and gotten
the desired results by hand. However, this takes forever and is a lot
of time and work. I need a mechanical solution. What kind of grinding
media, apparatus and such would work? I need to efficiently collect as
much silver as possible. Any ideas? Thanks, I appreciate it.
Also, if a ball mill would work, what would be the best grinding media
to use? Thanks again
I saw your post and have been trying to remember who it as that made a
process for making fine bronze powder for use in gold paint, it was
Henry Bessemer see http://en.wikipedia.org/wiki/Henry_Bessemer . Some
further information here but whether it'll be of use I don't know

How about a burr on a die grinder with external hose exhaust and a
cabinet to catch the dust, Parlous?
