Alumina Grinding Balls are abrasive media for faster grinding and precise and deep processing ceramic raw materials and glaze materials. They're built by isostatic pressure molding, with the purpose of making the grinding process more efficient. To achieve that, they're designed to diminish the loss of grinding media in fine crushing machines (such as ball mills, can-type mills, and vibration mills), surpassing common ball stones and natural cobblestones by far.
