Ceramic Ball are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as covering support materials and tower backings for catalysts in reactors. High temperature and high pressure resistance, low water absorption, stable chemical properties. It can withstand the corrosion of organic solvents such as acids and alkali and the temperature changes in the production process. The main function of the ceramic ball is to increase the gas or liquid distribution connection, support and cover the active catalyst. Classification of Ceramic Balls:Ceramic balls are classified according to their uses and can be divided into supporting ceramic balls and grinding ceramic balls.
