Wet ball milling's strong mechanical forces facilitated the breaking up of larger particles and the improvement of the particle size distribution. Furthermore, by exposing more surface area and changing the surface chemistry, wet ball milling may have an impact on the particles' surface charge ( Yang & Tang, 2021 ).
