Grinding Ceramic Balls
The alumina grinding bals 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 extraordinrily high density,high hardness,high wear resistance. During the abrasive/grinding proceses, ceramic ball will not be broken, it will not contaminated the materials to be grinded.
Type: According to the content of aluminum oxide: 60-70%, 65-75%,92%,95%
According to the size: D25mm-D75mm
