The technical ceramic alumina ball with the characteristics of high density,high hardness,low abrasion,good anti-seismic stability, corrosion resistanceis which can improve the ball milling efficiency of the ball mill, reduce the pollution of glaze slurry, improve the product quality and economic benefits of the enterprise that is made of selected high-quality raw materials, advanced molding technology and calcined in high-temperature tunnel kiln at 1600 �ºC. It is an ideal grinding medium for processing glazes, billets and various mineral powders.
The technical ceramic alumina ball is used in the grinding process of ceramic glaze, including the grinding process of ball mill. The semi-finished glaze slurry after grinding by ball mill is put into the mixing mill for fine processing, so that it becomes glaze. Or put the glaze powder directly into the agitation mill for fine processing to make it into glaze.

(1) Introduction: The inert alumina ceramic ball is broadly utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection etc. There are lots of merits for it, for instance, the stronger resistance to high temperature and high pressure, lower ratio of the moisture absorbing, more stable chemical properties, and so on. It is capable of enduring the corrosion of acid, alkali, and organic solvent. In addition, it can also bear the rapid transitions of temperature during the operation. In fact, its principal functions are to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which especially has the relevantly lower mechanical strength.

Compared with steel ball, Si3N4 ball has following advantages: 1. 59% lighter than steel ball, which means less centrifugal force and less wear on the groove during high speed and acceleration. 2. 44% larger elastic modulus, which means less deformation under load. 3. Harder with Rockwell hardness as 78. 4. Smaller friction coefficient. 5. Only 1/4 coefficient of thermal expansion of steel, can endure sharp fluctuation of temperature. 6. Superior surface finish can be achieved, Ra could be 4~6 nm. 7. Can endure high temperature with high hardness and strength up to 1050 degrees. 8. Never rust, and can roll without lubrication. 9. More corrosion resistant than steel. 10. Free of metal contamination. 11. Non-magnetic. 12. Electric isolation. 13. No adhesive-wear with metal. 14. Contact angular is very large with molten and nearly no reaction. All above combination makes Si3N4 to be first choice for high-demand bearing ball material and valve ball.

Active alumina can be used widely as excellent de-fluorine agent in drinking water, in the production of acid and in the production of alky benzene and the de-acid regeneration agent of oil transformer, in addition, active aluminum can also be used as drying agent,purifying agent, catalyst and their carrier in the industy of fertilizer, petroleum and chemisty. Active alumina cann¡¯t dissovle in water and organic solvent, but it dissolves in strong acid and alkli. It is tasteless and nonpoisonous and possesses high crush strength, strong hygroscopicity and can maintain original state instead of breaking into pieces after sucking up moisture.
