Ceramic alumina balls
Alumina Grinding Media have the advantages of high strength, high stabilities to chemical and thermal circumstances.
It can be resistant to acid, alkali, salt and all organic solvents. Being used as a support and a covering material in reactors in oil refinery, chemical, fertilizer, natural gas and environmental protection industries.

|Physical and mechanical properties|
Ceramic ball has been used widely used as supporting material at the reactor bottom in petrochemical, ball mills, pot mill, vibrating mill and other fine grinding plants as abrasive media for ceramic raw materials and glaze materials in ceramic, cement, glass, porcelain enamel, paints, pigments, chemicals, pharmaceuticals, paint industry, inks, cosmetics, inorganic mineral powders, fine chemical, coal-chemical, fertilizer, natural gas and environmental protection industries . etc.
Number and Size of the Balls
1.Pregrinding the coarse, hard material with large balls
2. Use of many small balls will increase the fine fraction if the running time is increased
3. A higher mass (spec. weight) of the grinding balls will accelerate the grinding
4. Size of the Grinding Balls
|Type of feed material|
Hard samples feed particle size<10 mm
30 mm or 40 mm
Medium piece size (<5 mm)
Fine material (0.5 mm)
10 mm or 5 mm
Homogenisation of dry or liquid samples
Homogenisation of viscous samples
These are just clues: the size of grinding jars and grinding balls should be determined experimentally if necessary.
Other Grinding Media:
Remark: In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used.
