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.

The manufacture of aluminum pigments involves a specialized ballmilling process as the first stage. Here the atomized aluminum is ballmilled in the presence of solvent and a lubricant for a period of five to 40 hours. The lubricant is employed to prevent "cold welding" of the aluminum particles and thus avoid agglomerates.
