The terms wet milling and dry milling are overarching concepts that do little to actually describe the processes and forces involved. But some methods are only possible under wet conditions, and some require dry milling conditions. Although the goal of both grinding methods is to reduce particle sizes to a target range, the processes are different.

A further important point of difference between wet and dry milling is that wet milling allows the easy introduction of surface active media for the reduction of the energy required to produce unit new surface or for the inhibition of aggregation of the fine particles.
