High Alumina Ceramic Grinding Ball
Product information
Alumina ceramic ball have the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand corrosion by acids, alkalis and other organic solvents, and can withstand temperature changes in the production process. Its main function is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.
Advantage:
Suitable for air separation equipment accumulator and steel plant blast furnace gas heating furnace as heat storage filler.
1-High strength
2-High thermal conductivity and heat capacitywear-resistant
3-Good heat storage effect
4-Good thermal temperature
Application
Alumina ceramic ball, widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as the catalyst in the reactor covering support material and tower packing. Its main function is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.
