Wet milling, also known as wet grinding, is a process through which particles that are suspended in a liquid slurry are dispersed in that liquid by shearing or crushing. Once the milling process is complete, these particles are ready for use or can be dried and separated for incorporation into additional products. Wet milling is more complex ...

In this study, ultrathin and easily dispersible gC 3 N 4 nanosheets were obtained by a simple wet ballmilling process. Morphological and structural analysis showed that increasing ballmilling speed resulted in a decrease in both particle size and the number of stacked layers in gC 3 N 4 nanosheets, hence improving their dispersion stability. Thinner nanosheets obtained by ball milling at ...

In wet ball milling, the dispersion of the particles in a liquid phase occurs by shearing, crushing or attrition, and this dispersion is exposed to the grinding media until the particle size target is met. The use of a liquid phase makes wet milling a more intensive process than dry milling and allows for extremely small particles, even at the ...
