Wet vs Dry Grinding - bulk-online Forums

2012-1-30 · Hope I'm posting in the correct area. I would like to know what the advantages of wet grinding compared to dry grinding are (if any). Would one expect wet ground material to exhibit different leaching characteristics from dry ground materials, even when particle size distributions are identical? I'm dealing with uranium ores in a lab scale ball mill (Bond Ball Mill).
