Hi guys,

A workshop near where I live produces a lot of brass swarf which is
then sold as scrap.

Bearing in mind that brass is a ductile metal, what is the best way to
grind the swarf into ~300 mesh or finer powder?

Will an arrangement similar to a peppercorn or coffee grinder work, or
will it just spit out the brass pretty much unchanged due to the
alloy's ductility?

Thanks.
James
