Our alumina ball is one ideal ball mill grinding media, it has excellent high density, high hardness, and high wear resistance. Alumina grinding ball is ideal for both wet and dry milling. Alumina balls are widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in Ceramic, cement, glass and enamel factories. Alumina Ball can also be used as Metal filtration and Burners in aluminum industry, chemical industry, etc.
