Nanoparticles tend to agglomerate, making them difficult to disperse after grinding. Wet milling addresses this by encapsulating each nanoparticle in the liquid slurry. On the other hand, wet milling presents the possibility of introducing dispersant and surfactant additives into the final product. Dry methods like jet milling can achieve the ...

Step 1: Wetting. The first step to wet grinding is eliminating air from the surface of the raw feed, so that each individual particle is fully in contact with the liquid slurry. Ensuring complete contact is vital for effective milling. This requires a liquid with lower surface tension than the free surface energy of the solid.
