Alumina ceramic ball

widely applied in fertilizer, gas and environmental protection industries.

Inert alumina ceramic ball

With the characters of high mechanical strength, high chemical stability, and excellent heat endurance, inert alumina ball can resist high temperature, high pressure, acid, alkali, salt and various organic solvents. 

The alumina grinding media is developed originally to meet the requirement from the ceramic tile industry for increasing productivity of frit and pigment grinding. Compared with the natural cobblestone, the alumina grinding ball has more outstanding and reliable performance. Choose alumina grinding ball as your ball mill grinding media can significantly increase productivity, saving time and power and the alumina grinding media is more environment friendly.

.

Therefore, it's widely applied in petrochemical, chemical, fertilizer, gas and environmental protection industries.
