A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

Fig. 2 shows the timewise evolution of the cumulative PSD experimentally obtained from the laboratory batch ball mill with different single ball sizes (, d B = 20, 30, and 40 mm) using steel balls and alumina balls. As milling progressed and finer particles were generated by breakage, the PSD shifted to the left monotonically even in the fine particle size domain (1100 μm).

Ceramic bead, hard metal shot, carbide balls, and other ballshaped media are used. The hardness of the powder or bulk material to grind determines the selection of the media material. Specifications Ball milling processes can disperse or mix pigments or fillers into resins, paints, coatings, plastics, rubber, or adhesives.

In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
