Dry Grinding VS Wet Grinding. An examination of the literature shows, however, that the actual difference between the results of wet and dry milling are often very large; for example the power to drive a tube mill in which a given material is being wet ground may be as much as 30 % less than that of a similar mill dry grinding.

The choice between wet and dry milling is, in general, unimportant in smallscale milling but is a major technical problem when largescale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the ...

· 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?

To do otherwise—that is, to run both wet and dry—might result in shocking a hot tool with coolant, potentially accelerating tool failure. If for some reason a part does calls for dry machining in one region of the part followed by wet machining in another, the shop is careful to insert a delay into the process to let the tool cool down gradually before coolant is applied.
