Crushing eggshell for snail jello

Bake them first. I stuff one half into the other then do the same to the next egg and stuff it into the first, repeat for all vacated shells. Then stick that stack on whichever oven rack you use least. Next time you bake or broil something they're taken care of as well.
As to how fine you need them to be, I dunno. I just use them in compost--crush them in hands, preferably while wearing an oven mitt as they can be sharp and ouchie. Brush into compost bin & done. That gets them down to maybe quarter inch size or so.
For your purposes the rolling pin might work. Put them in a ziplock bag and press all the air out before rolling or bits will go shooting off in an annoying manner. They wind up either in your eye or on the floor waiting for the next person to walk barefoot in the area.
but if you need them really powder-fine you should go to the next step: electric grinder most commonly used for whole-bean coffee. Toss them either pre-squished (a step most helpful for releasing anger, hostility, etc) or just halved as they come out of the baking step. Since they're dry they won't stick to the grinder blades or bin after you're done.
If you're pinched for money you could try a pepper grinder but I don't know how well that would work. And if you are talking large numbers of eggshells it would get a bit tedious. Best of luck.

I use a coffee grinder. It chops the shells into a powder and cleans your grinder as a bonus. Alternatively, you can make plaster of paris in bathroom dixie cups and use those for your snails. It lasts over a month.Using it as a calcium supplement. How finely crushed will the eggshells need to be? I have a dough roller
I bake mine also before crushing. Only takes about 15 min at 350.
I use a blender but it doesn't get them powdery-fine. What coffee grinder are you using to turn them into powder? Doesn't the P-O-P cloud the water?
thanks for the replies
the plaster of paris thing is interesting...a quick google search shows that it's affordable :O
is it used just to provide calcium, or can it be as healthy food?
