Grinding Alumina Ball has excellent high density, high hardness, and high wear resistance. Alumina balls are widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in Ceramic, cement, glass, and enamel factories.
Metal filtration Alumina Ball from Sinabuddy has ultra-low porosity, very high density, and outstanding thermal shock resistance. It is the primary filter media for deep bed filtration systems.
Regenerative Burners Alumina Ball has high strength, large thermal conductivity, heat capacity, good heat storage and stability. It can pre-heat both coal gas and air to rapidly increase the combustion temperature to meet the billet heating requirement. It also used as heat storage packing in steel industry.
