In dry grinding, reagglomeration can be somewhat mitigated by the addition of grinding aids to lower surface energy [32], but even with this, the residual effect leads to a much higher practical grinding limit compared to wet grinding, resulting in substantial efficiency drops at finer sizes [33]. However, in some cases dry grinding is prudent ...

Wet milling, sometimes referred to as wet grinding, is a procedure whereby shearing or crushing is used to disperse particles that are suspended in a liquid slurry. These particles can be used right away when milling is finished, or they can be dried and separated to be added to other goods. Advantages of pharmaceutical wet milling:
