Refining Fine Grog How to make it finer?

But I would assume the grog would wear the balls and jar significantly.
Maybe you could find the perfect sized sieve and wet sieve out the finer stuff leaving the more rough stuff, but i would assume that the saze of the grog is mostly even so this would be a huge waste of time.

As you state it your problem is one of size classification. What mesh size range is the grog supposed to be. "Fine" is only a relative term.
Grog can be supplied in a size range such as 40~60 mesh so that all the particles fit through a 40 mesh sieve but not through a 60 mesh sieve, or it can be supplied as a mesh size and smaller such as 40F (40 mesh with all finer particles included. everything passes through a 40 mesh sieve).
You could try sieving a small sample like 100 or 1000 grams to determine what size range you have. If you run it through a 40 mesh sieve and nothing gets stuck on the screen move up to 60 mesh etc.
Feel the results of each sieving and when you find one that is fine enough to suit you sieve the lot. Now you'll have a conundrum. What to do with the stuff that isn't fine enough?
How much are we talking about here? 5lbs or 50? For 5lbs I'd say mortar and pestle made from porcelain and fired high. For 50lbs... I have no idea. I guess sieve it and throw out the big stuff.
My 2 cents,

just seems like a waste of time IMO trying to mill your own grog and minimize the dust hazard.
