Wear-resistant ceramic ball
Time:2012-9-07  Posted By:The Pingxiang City Thiel Ceramic Manufacturing Co., Ltd.  Attention: 1403

The alumina grinding balls 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: Φ25mm-Φ75mm.
