Inert Ceramic Balls
1. 20years professional manufacturer
2.For Catalyst Bed Support
3.High Strength
4.Acid Resistance
1. Inert Ceramic Balls:
To be used in catalyst bed support and tower packing.Inert Alumina Ball is widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection etc. With functions as covering and supporting materials for catalyst in reactors and packing for towers. The main role of inert alumina ball is increasing the distribution of liquid and gas, holding and protecting the activated catalyst with low strength.
To meet the requirements of different customers, We have developed large series of patent ceramic balls, utilized in chemical, petrochemical, fertilizer, fine chemical sand environmental protection industries.
