Alumina Grinding Balls

ALUMINA GRINDING BALL FOR CEMENT INDUSTRY We apply the nanometer technology and ceramic composite technology for producing the alumina grinding balls which are used the cement industry. They have the characteristic of high bulk density low wear loss, low breakage. Compared with steel balls, the alumina balls are more energy-efficient, and they are widely used in the cement plants as well as in the dry grinding of other material.
