Alongside the mining industry, ball mills are also used in different sectors, such as cement production, for grinding clinker and other raw materials; ceramic manufacturing, for grinding and mixing ceramic powders, and paint production, for dispersing and homogenizing pigments and other ingredients.
A variety of techniques ensure the preparation of solid dispersions, e.g., hot melt extrusion, spray drying, the solvent evaporation method or supercritical fluid precipitation [47,[49][50][51][52].

The ceramic ball mill is a kind of ball mill grinder that the liner plate is made of wear-resistant ceramics. It has a small capacity, suitable for small batch production, and it can realize a 24-hour continuous work with dry grinding or wet grinding.
In this work, a titanium boron carbonitride advanced ceramic was successfully synthesised by a solid-gas mechanochemical reaction in a planetary ball mill from a mixture of elemental Ti, B, and C under nitrogen atmosphere. This material, with a general formula of Ti(BCN), exhibits a face-centred cubic structure (NaCl type) that is …
His team investigated whether a catalytic reaction in such a mill works better because the catalyst is always given a fresh surface where the reactants can meet. They used a soft alumina (gamma-alumina) mixed with gold particles as a catalyst and followed the process in the ball mill with various analytical methods.
