Alumina grinding balls are widely used in ball mills as abrasive media for ceramic raw materials and glaze materials. Ceramic, cement and enamel factories as well as glasswork plants use them because of their excellence of high density, their high hardness, and their high wear resistance. During the abrasive/grinding processing, ceramic balls will rarely be broken and the contamination factor is minimal.

Alumina Lining Brick can be divided into rectangular brick, trapezoidal brick and irregular brick as shape. The product has the high hardness, density, wear low, the neat degree good, anti-corrosion.
