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.

Not easy, I suspect.

ISTR that some things are chilled to liquid nitrogen temperature, which
makes them much more brittle, before grinding. No idea if this would
work for brass (and would probably depend on the alloy).
