Wet Ball Mills are Ball Mills that are used widely in the ore beneficiation industry,as well as the building material industry such as glass.. During the producing phase, the material and water are mixed together to grind in the ball mill. Under the effect of the flowing water,the material will get a better flow ability so the processing capacity will be higher.

Dry vs. wet grinding Dry grinding would give strictly abrasive wear. The ball wear was studied with a taconite sample during dry and wet grinding with mild steel balls. The wear rate was markedly higher for wet grinding (37.1 mg h - ] ball- 1 ) than for dry grinding (5.4 mg h-1 ball-1).

In general terms, the abrasive grit size range for grinding wheels runs between 12 grit for rough grinding operations, such as those found in steel mills, and 220 grit for very fine/precision grinding operations. Again, there is no industry standard, but in general terms: Coarse grits run 12 to 24. Medium grits run 30 to 70.
