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.

Ball mill is typically used to grind and/or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

A wetrotating disc milling was used as a method to prepare ceramic slurry. The rheological measurements of the milled slurries showed that the apparent viscosity of the wetrotating disc milled slurry was low and the slurry was nearly Newtonian behavior, whereas that of ballmilled slurry was more viscous and the slurry exhibited a very strong shear thinning effect.
