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.

An innovative approach for using ceramic balls instead of cylpebs as grinding media in the wet ball mill based on the ball size and the ratio of the total mass of cylpebs was proposed. Therefore, ceramic balls can be used in wet tumbling mills to replace cylpebs as finegrinding media. This result has also been verified in industrial applications.
