Melamine tray customers, We have developed large series ofpatent ceramic balls, utilized in chemical, petrochemical,fertilizer, fine chemical sand environmental protectionindustries.

Inert Alumina Ceramic Balls broadly utilized as the covering orsupporting materials of the catalyst in the reactors and thepacking in the columns in such varied areas, for example,petroleum, chemical industry, chemical fertilizer, natural gas, andenvironmental protection etc. There are lots of merits for it, forinstance, the stronger resistance to high temperature and highpressure, lower ratio of the moisture absorbing, more stablechemical properties, and so on. It is capable of enduring thecorrosion of acid, alkali, and organic solvent. In addition, it canalso bear the rapid transitions of temperature during theoperation. In fact, its principal functions are to accelerate thedistribution of gas or liquid, and support or protect the activecatalyst, which especially has the relevantly lower mechanicalstrength.
