Alumina ceramic ball

widely applied in fertilizer, gas an environmental protection industries.

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. As the material to support and cover catalystin the reactor,  inert alumina ball can buffer gas or liquid's flush on catalyst so as to protect catalyst. It also can improve distribution of gas or liquid in the reactor.

Common Alumina ball: Alumina ball are the simplest, regularly shaped packing, Packed beds consisting of balls have a relatively small surface area per packed volume. Owing to the extremely small void fraction within the packed bed. The pressure drop is relatively high, Balls are frequently used as catalyst carriers and to smooth flows.

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