Alumina ceramic balls are high-quality ceramic grinding media made from high-purity alumina as the main raw material, through fine formulation, molding and high-temperature sintering processes. Alumina ceramic balls produced by Shandong Bairui have extremely high hardness, excellent wear resistance and chemical stability, and are ideal for various grinding, dispersing and catalytic applications.
Excellent wear resistance
Excellent chemical stability
High density and high strength
Precise size control
Extremely long service life
