The alumina ball is mainly the diameter of 2 ~ 60mm, divided into rolling and isostatic pressing molding, high-temperature sintering and high quality grinding medium. The product advantages in wear significantly, with less wear, high strength, corrosion resistance, low price, stable product quality, than the characteristics of major appearance, gloss, widely used in ceramics, special ceramics, refractory materials, chemical industry, non-metallic mineral industries.
