Ball Mills. 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.
