How to grind large quantity of rock salt

Hello - I had previously obtained a 20 pound bag of very coarse Himalayan salt for a ridiculously low price. I am wanting to grind it and give some of it away as gifts. Not everyone has a salt mill so I did not want to give them the coarse salt. Any recommendations on a particular mill or way to grind such a large quantity of salt? I think using a mortar and pestle would be too labor-intensive as well as using a small salt mill.
Thanks for any feedback - JD

  1. Hmmm.. coffee grinder, or could you just throw it in the food processor, a pound at a time, for a while, that should do it..

      I thought about that - probably the best option as long as I am diligent to clean the equipment ASAP to avoid corrosion.
      Thanks, JD

        I vote for the food processor, you should be done pretty quick. Just throw it in the dishwasher when you're done, not much chance of corrosion anyway.

      2. do YOU have a salt mill? Chuck that rascal onto a drill/driver and grind away. I use this alton brown method often to grind large quantities of black pepper...works like a charm. Food processor would be the absolute quickest, tho you'd have to watch it closely so as not to make himalayan salt powder

          That sounds like a great idea. Unfortunately, I only have a small Kyocera grinder that does not have the means to attach a drill. Any recommendations on a particular mill?

            ah, I see...I just saw a photo of the kyocera. For the drill trick to work, a grinder with an axial mechanism, like a firth or a peugeot would be needed. Looks like its hello food processor!

          1. Thanks for all the suggestions. I will start with the food processor and see how that works before I invest in a mill. Much appreciated, JD

            1. I guess my preferred method, using what you're likely to have, would be a food processor, though I suspect you're gonna put some serious wear and tear on the blades doing that.

              The other option I would suggest looking into is seeing how cheaply you can buy salt mills in bulk. A restaurant supply store might have a decent deal - theyre not necessarily very expensive. Then you could give the salt away in the salt mills as a rather nicely packaged present.

                That's a great idea! Wish I had thought of it myself!

                  I agree that grinding twenty pounds of rock salt is going to have you looking at replacement blades for the food processor, and possibly a scuffed work bowl, too. For a job like this, I'd consider getting a new, suitable mill and using the drill approach. That really "rocks" (ahem).

                  The bulk salt mills idea is also cool, but it's hard to imagine that gift-worthy mills could be that cheap. Maybe if you were only intending to give away a few gifts from your 20lb of salt?

                2. Don't put this stuff in your food processor. The rock salt is definitely comparable in hardness to rocks-- if you try to hit it with an implement less sturdy than a hammer you will see. I didn't experiment with the hardness before hand and put the rocks in my BlendTec blender and the rocks punched a hole clear through the side of the jar. The blades/engine could handle it but the jar couldn't. A plastic food processor jar would obviously do similar.

                  Given the toughness of them even when hit with a hammer, I wouldn't try it in a glass-walled jar either, unless you like shattered glass all over your kitchen.
