1. Product Description

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 glass work owing to the excellence of high density, high hardness, high wear resistance. During the abrasive/grinding processing, ceramic balls will not be broken, it will not pollute the 95%material to be grinded.

 

2. Type

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

According to the specification: 10mm-75mm.
