Alumina Grinding Balls

Alumina Grinding Balls
Product Detailed
excellence of high density, high hardness, high wear resistance.

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 excellence of high density, high hardness, and high wear resistance. During the abrasive/grinding processing, ceramic balls will not be broken; it will not pollute the material to be grinded.

According to the content of aluminum:60%-70%,65%-75%,92%-95%According to the specification:D25mm-D75mm
