Product Introduction
Zirconia grinding balls are a particularly tough ceramic material, with hardness and wear resistance close to that of ruby. They are currently a very advanced and ideal grinding medium internationally and serve as an upgrade to traditional grinding media. This product is made from YL-TZP Zirconia Ultrafine Powder A high-tech grinding medium manufactured through spray granulation, isostatic pressing, and high-temperature sintering processes.
Currently, the high-purity zirconia 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. Choosing our products will definitely greatly reduce comprehensive costs such as media wear, power consumption, labor, and equipment, doubling output without adding any equipment, and significantly improving product quality. Widely used in electronics, deep processing of non-metallic minerals, sanitary ceramics, coatings, inks, papermaking, fillers, dyes, zirconium silicate powder, calcium carbonate, food, pharmaceuticals, health products, cosmetics, and various grinding machines in laboratories.
Product Features
Suitable for grinding materials with high hardness and viscosity
High specific gravity (density 6.05 ), the heavier the grinding beads, the greater the grinding shear force provided, improving grinding efficiency
Resistant to acid, alkali, and salt corrosion, smooth surface, easy to clean
High mechanical strength, impact resistant, does not break during high-speed operation
Wear resistance: compared to glass beads 30-50 times, zirconium silicate beads: 8 about times
Grinding efficiency: compared to 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 ” ", with product quality reaching international advanced levels. Widely used in coatings and inks, pesticides and chemicals, ceramics industry, non-metallic mining, food industry, nanomaterials, and other industries.
