Zirconia Grinding Ball is engineered for precision milling of advanced materials where purity, durability, and consistency are critical. With exceptional hardness and chemical stability, it ensures minimal contamination in sensitive applications such as battery slurry, ceramic pigments, and catalysts. Its high density allows efficient energy transfer, making it the preferred choice for planetary mills, horizontal mills, and other industrial grinding systems.
Zirconia Grinding Balls Benefits
- With a density of ≥6.0 g/cm³, Zirconia Grinding Ball achieves superior energy transfer, leading to shorter grinding cycles. This density is about 30% higher than alumina media, reducing milling time significantly.
- The compact structure ensures efficient particle size reduction in both wet and dry milling. Tests show up to 20% faster throughput in horizontal mills compared with lower-density beads.
- Zirconia Grinding Ball has a Vickers hardness of >1200 HV, ensuring long service life under continuous milling stress. Compared to glass beads, durability is extended by 5–10 times in high-speed mills.
- Independent test data confirm that Zirconia Grinding Ball retains over 95% of original mass even after 500 hours of milling.
- Chemically inert and metal-free, Zirconia Grinding Ball keeps heavy metal impurities below 0.01 ppm, meeting purity requirements for advanced materials.
- Uniform roundness and smooth surfaces reduce abrasion loss to ≤0.01 g/kg per milling cycle, lowering contamination compared to traditional beads.
