    Chemical parameters of Alumina grinding ball:

    1. High density ≥ 6.02g/cm3

    2. Very high wear and tear resistance;

    3. Highest operating time is achievable;

    4. Low contamination of the grinding product, therefore useable for high-grade grinding of pigments,dyes,pharmaceutical and cosmetic products;

    5. useable for all modern types of mills and high energy mills(vertical and horizontal);

    6. excellent crystal structure avoids bead breakage and reduces the abrasion of mill parts;

    7. no radioactivity in comparison to ceramic beads made of zirconium silicate and therefore no contamication of the grinding product and no costly disposal of the beads.
