Compared with glass beads, alumina balls and zirconium silicate balls, ZrO2 grinding balls show outstanding durability and wear resistance. Its service life is 5–10 times longer than glass beads and 8 times longer than ordinary zirconium silicate media.
The high-toughness sintered structure prevents cracking and peeling during high-speed stirring and impact grinding, maintaining complete spherical shape for a long time. The ultra-low wear rate avoids excessive media loss and frequent replacement, greatly reducing equipment downtime and comprehensive operating costs. Meanwhile, the smooth and dense surface will not produce impurity shedding, ensuring zero pollution to grinding materials.
These ZrO2 grinding balls are tailored for high-standard wear-resistant grinding scenarios. In new energy industry, they are used for fine grinding of lithium battery positive and negative electrode materials. In chemical and coating industries, they adapt to grinding of paints, inks and pigments with strict purity requirements. They also apply to pharmaceutical fine powder processing, cosmetic raw material dispersion and advanced ceramic powder grinding. With excellent acid and alkali corrosion resistance, they stably adapt to various complex grinding environments, realizing high-efficiency and long-cycle production.
Adopting yttria-stabilized zirconia formula and high-temperature dense sintering process, the product has ultra-high hardness and structural toughness, with far lower wear rate than ordinary ceramic media, resisting impact and friction loss in long-term grinding.
Yes. The products feature stable performance and low fatigue loss, supporting 24-hour continuous operation. Their long service life effectively reduces media replacement frequency and improves industrial production efficiency.
No. The high-purity ZrO2 material is chemically inert, with no metal precipitation or powder shedding during grinding, which fully meets the purity requirements of pharmaceutical, new energy and fine chemical materials.
Standard available sizes range from 0.8mm to 30mm. Custom sizes can also be provided according to specific industrial fine grinding requirements.
The maximum operating temperature for these ZrO2 grinding balls is up to 2200°C, maintaining outstanding physical and chemical stability under extreme thermal conditions.
They are mainly used in new energy (lithium battery materials), chemical & coatings (paints, inks, pigments), pharmaceuticals, cosmetic raw material dispersion, and advanced ceramic powder processing.
