Featuring transformation toughening structure, the zirconia grinding balls show outstanding impact resistance and structural stability. Their service life is 5-10 times longer than glass beads and 8 times longer than zirconium silicate beads, maintaining over 95% original mass after 500 hours of continuous milling.
With ultra-low wear rate and smooth seamless surface, they avoid particle shedding and medium pollution. Meanwhile, the high-density structure provides strong shearing and crushing force, improving grinding fineness and uniformity while boosting overall production efficiency. Their excellent acid and alkali corrosion resistance adapts to diverse complex grinding environments.
These durable grinding balls are widely applicable in fine grinding and ultra-fine dispersion industries. In new energy materials, they process lithium battery cathode and anode materials to ensure high purity and fine particle size.
In coating, ink and pigment industries, they realize uniform dispersion of colorants to stabilize product color quality. They also serve precision fields including electronic ceramics, pharmaceutical raw materials and food additives, as well as traditional industries like mineral processing and chemical powder processing, fully meeting long-cycle and high-precision grinding demands.
Adopting Y-TZP ceramic formula and high-density sintering process, the balls have ultra-high hardness and toughness. The unique transformation toughening property resists impact damage, with far lower wear rate than glass, steel and ordinary zircon media, realizing long-term continuous use.
Yes. The product features stable chemical inertness, no metal precipitation and ultra-low wear. It will not react with acid, alkali or organic materials, effectively avoiding impurity pollution, which is critical for high-purity material production.
We support full-size customization from 0.1mm to 50mm. Micro-sized balls suit ultra-fine grinding, while large-size ones adapt to coarse crushing and high-load industrial milling, covering all grinding process demands.
The maximum working temperature for these yttria-stabilized zirconia grinding balls is up to ≤1200℃, enabling them to maintain excellent physical and chemical stability even under intense high-temperature processing environments.
These Y-TZP grinding balls feature a high density of 6.0 g/cm³, a Vickers hardness of ≥1200 HV, and a wear rate of ≤0.01%/24h, providing extreme shearing force and long service life.
They are widely utilized across new energy battery materials, coatings, inks, pigments, electronic ceramics, pharmaceuticals, food additives, as well as mineral and chemical powder processing industries.
