a process for the wet grinding of pigments which comprises effecting the grinding in an aqueous medium containing 0.1-20 percent of a base selected from the group of water soluble alkali metal-, alkali earth metal- or ammonium compounds. the addition of bases inproves the transmission of grinding energy to the material being ground and results in the production of purer pigments of better

Particle size reduction, screening and size analysis

In wet grinding, the surrounding medium is liquid, as opposed to dry grinding. Wet grinding should be considered in cases where the material is prone to static charging, or when the material is toxic and dust containment is difficult. Also wet grinding can be used when the final product size is extremely fine since production of nanoparticles
