wear-resisting ball
The alumina grinding ball
The alumina 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 excellence of high density, high hardness, high wear resistance. During the abrasive/grinding processing, ceramic balls will not break up, it will not pollute the grinded material as well.Type：According to the content of aluminum：55-65%、65-75%、92%、95% According to the specification：ф19mm-ф60mm Wear-resisting main technical parameter of ball
