2018-3-1 Wet ball-milling is to be added a certain amount of solvent (distilled water, anhydrous ethanol, acetone, etc.) into the milling system . The advantage of wet ball-milling compared with the dry ball-milling is good slurry fluidity and homogeneity, especially for multiphase precursors.
Ball mills are common grinding equipment in mineral processing industries. Ball wear results from three mechanisms namely impact, abrasion and corrosion.
