Ceramic ball include packing ceramic ball and grinding ceramic ball. The grinding ball has been widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glasswork owing to the extraordinarily high density, high hardness, high wear resistance. During the abrasive/grinding processes, ceramic balls will not e broken, it will not contaminate the materials to be grinded. Type: According to the content of aluminum oxide: 60-70%, 65-75%, 95%, 95% According to the sizes: 25mm-75mm. The packing ball can also be called inert ceramic ball, activated ceramic ball, refractory ceramic ball, thermal-storage ball etc. To meet the operating requirements of different service, we have developed large series of patent ceramic balls, utilized in chemical, petrochemical, fertilizer, fine chemicals and environmental protection industries.
