Alumina grinding balls are widely used in ball mills as abrasive media for ceramic materials and enameling materials. Ceramic, cement and enamel factories as well as glass factories use them because of their high-density excellence, high hardness and high wear resistance. During the abrasive / grinding process, the ceramic balls will rarely break and the contamination factor will be minimal.
Alumina lining brick
The alumina facing brick can be divided into rectangular brick, trapezoidal brick and irregular shaped brick. The product has high hardness, density, low wear, good grade, anti-corrosion.
