Corundum and corundum-mullite AL2O3 porcelain balls and porcelain lining bricks are most suitable to be used as grinding media and drum linging of various grinding equipments because of its excellent properties such as high strength,high hardness,high abrasion resistance, high gravity, small size,high temperature resitance.
Application: It is mainly used for non-metalmineral products extra refining, it is ideal grinding media for stirring grinding, sand grinder and vibeation grinding. And it is widely applied in ceramics, paint, ink coatings,dyes, rubber and power industries.
Performance:
1. High density and hardness,impact resistance, low loss rate, smooth surface and no contamination to products.
2. Fine chemical stability, anti-corrosion..
3. Under condition of appropriate ball size ration, it can achieve high grinding efficiency with material results D¡Ü2¦Ìm.
4. High performance and low price.

The alumina packing ball takes super fine alumina powder as main raw materials and shapped by isostatic pressures and rolling machinery and baked in tunnel kiln by high temperature. It is widely used as the packing and activator in petroleum and chemical industry. It is suitable for chemical fiber factory, alkyl benzene factory, aromatic hydricarbon factory, ethylene factory, natural gas factory etc. As the pad bottom fills in the material to catalyzes heavily to get one¡¯s thing to ready replace, isomerization device, the shed methyl device etc.

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.
