These ZrO2 beads boast outstanding wear resistance and structural toughness, with a service life 2-10 times longer than ordinary ceramic beads. Their high density provides powerful kinetic energy for efficient ultra-fine grinding, suitable for high-viscosity and high-hardness materials. Excellent acid and alkali corrosion resistance and zero metal ion dissolution ensure raw material purity. Additionally, their high roundness and smooth surface reduce equipment abrasion, lowering overall operational and maintenance costs.
Tailored for wear-resistant high-performance scenarios, the beads are widely applied in new energy battery materials, industrial coatings, printing inks, pharmaceutical and cosmetic fine processing. They also serve precision ceramic materials, magnetic materials and pigment dispersion industries. Perfect for high-speed wet milling and ultra-fine grinding processes, they meet strict requirements for product fineness, stability and low impurity in high-end industrial manufacturing.
It integrates high hardness, low wear rate and high density, achieving higher grinding efficiency with less contamination and longer service life, perfectly fitting high-performance wear-resistant processing needs.
They adapt to high-viscosity coatings, battery electrode materials, fine pigments, pharmaceutical powders and precision ceramics, covering most high-end ultra-fine grinding and dispersion scenarios.
Match bead size with grinding fineness requirements, avoid excessive equipment speed, and maintain clean grinding materials to reduce abnormal wear and impact damage.
The particle size ranges from 0.1 mm to 20 mm, catering to various requirements from ultra-fine nanometer milling to larger particle dispersion.
No. With zero metal ion dissolution, an extremely low wear rate (≤4 ppm/hr), and acid-alkali corrosion resistance, ZrO2 beads preserve the purity of raw materials.
With a density of 5.8-6.0 g/cm³, the beads deliver powerful kinetic energy upon collision, greatly boosting milling efficiency even for high-viscosity and high-hardness slurries.
