Zirconia alumina composite ceramic balls and zirconia beads are a particularly tough ceramic material, with hardness and wear resistance close to that of ruby. They are currently very advanced and extremely ideal grinding media internationally, and also represent an upgrade from traditional grinding media. At present, the zirconia alumina composite ceramic grinding balls produced by our factory are mainly used in the electronics industry, coatings, inks, papermaking, fillers, dyes, and other industries, as well as in research institution laboratories, for ultrafine grinding in ball mills, vibratory mills, planetary mills, and stirring mills.
Product Features:
Suitable for grinding materials with high hardness and viscosity
High specific gravity (6.05); the larger the grinding bead mass, the greater the grinding shear force provided, improving grinding efficiency
Corrosion resistant to acids, alkalis, and salts; smooth surface, easy to clean
High mechanical strength, impact resistant, does not break during high-speed operation
Wear resistance: 30-50 times that of glass beads, about 8 times that of zirconium silicate beads
Grinding efficiency: 10-12 times that of glass beads, 4-6 times that of zirconium silicate beads
Common specifications: Ø0.2-60mm
Applicable Equipment Fields:
0.5-3mm spherical grinding media suitable for sand mills
5-20mm spherical grinding media suitable for stirrers and rolling ball mills
Spherical grinding media above 20mm suitable for rolling ball mills
Widely used in coatings and inks, pesticides and chemicals, ceramics industry, non-metallic mining, food industry, nanomaterials, and other industries.
