ADVANTAGES:
Ceramic balls are characterized by its high strength, low abrasion loss, large heat capacity and thermal conductivity result in efficient heat storage performance, excellent resistance to high temperature and the thermal shock. The balls have been effectively used in recuperator in air separation process, and also used to pre-heat the gas and the air in coal gas heating furnace in iron and steel plant.
