What's the best way to grind up a block of Himalayan salt? Meat grinder? Cheese grater? Vitamix? Hammer?

Chisel and hammer into smaller pieces. Then crush in blender or even better, Vitamix. Spare the meat grinder.

I grind it on a microplane.

I'd make sure it's been crushed up pretty good with a hammer before putting it in a Vitamix or Food processor.
I ruined a blade on a older model Vitamix trying to grind some Parmesan cheese rinds. Apparently, according the VHS tape it can turn wood into sawdust but not so much cheese.
