Composite Ball Ceramic Ball It is a particularly tough ceramic material, with hardness and wear resistance close to ruby. It is currently a very advanced and extremely ideal grinding medium internationally, and also an upgraded product of traditional grinding media. Currently, our factory produces high-purity zirconia grinding media balls mainly used in the electronics industry, coatings, inks, papermaking, fillers, dyes, and other industries as well as research institution laboratories, for ultra-fine 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 (density 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 fracture at high speed operation
Wear resistance: is glass beads 30-50 times, zirconium silicate beads: 8 about times
Grinding efficiency: is glass beads 10-12 times, zirconium silicate beads: 4-6 times
Compared with other ceramic grinding media, zirconia beads have three outstanding features: first, high density; second, high hardness; third, good toughness. Although the procurement cost is relatively high, the overall usage cost is very advantageous, especially suitable for occasions requiring low impurities.
Application Industries
The high-purity zirconia balls produced by our company use high-purity zirconia powder and adopt " titration method, sintering method, isostatic pressing method ” ", product quality reaches international advanced level. Widely used in coatings and inks, pesticides and chemicals, ceramic industry, non-metallic mining, food industry, nanomaterials, and other industries.
