The ceramic ball is made of materials such as AL2O3, kaolin, synthetic aggregate, mullite crystal, etc. It is made by rolling and pressing. The product has the advantages of high temperature resistance, corrosion resistance, high density, low thermal resistance, high strength, good thermal conductivity, oxidation resistance, strong slag resistance, large thermal conductivity and heat capacity, high thermal storage efficiency; good thermal stability, not easy to break due to temperature changes. The specific surface area can reach 240m2/m3. When in use, many small balls divide the airflow into very small streams. When the airflow flows through the heat storage body, a strong turbulence is formed, which effectively breaks through the surface of the heat storage body. Because of the small ball diameter, small conduction radius, small thermal resistance, high density and good thermal conductivity, it can meet the requirements of frequent and rapid reversal of heat storage burners.
It is widely used in industries such as petroleum, chemical industry, fertilizer, natural gas and environmental protection as a covering support material and tower filler for catalysts in reactors. It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the erosion of organic solvents such as acids and alkalis, and can withstand temperature changes during the production process. Its main function is to increase the distribution points of gas or liquid, and support and protect the active catalyst with low strength.
