I need to crush about 10 kilos of iron pyrite and get it into a fine powder, a little bit finer than sand. What kind of service or machine should I be looking for? I tried "rock milling" and "rock crushing", but most of these machines are too big for what I need. I tried "rock powdering" but most of my search results are for making crack cocaine instead...
I'd buy some crack OP, how much you want?

This. You can probably DIY one if you don't mind doing it in small batches (and the noise).
just experiment. i made this to turn dried red dirt clay into a fine powder to use in a refractory for my aluminum melter. spun in an old clothes dryer. homemeade ball mill of sorts

Looks terrifying, and very effective I bet.

it worked great, i think i ended up adding some 2 cycle oil to the sand to make greensand for casting, and it worked really well.
looks like a torture device for sure

Looks like one of Niles Crane's places - before the divorce with Maris.
