This series of zirconium oxide balls stands out for its remarkable high hardness and grinding efficiency, fully aligning with the core positioning of high-performance grinding media. The ultra-high Vickers hardness enables them to grind hard materials such as ceramics, minerals and alloy powders easily, avoiding deformation or breakage during high-intensity grinding. Their dense structure and smooth surface minimize friction loss, significantly accelerating grinding speed and improving grinding uniformity, while ultra-low wear rate extends service life and cuts down replacement and maintenance costs. Excellent chemical inertness also guarantees no contamination to ground materials, maintaining material purity throughout the grinding process.
With high hardness and efficient grinding properties, these zirconium oxide balls are widely applied in multiple industries with demanding grinding requirements. In the new energy battery industry, they are used for high-efficiency grinding of electrode materials, ensuring uniform particle size and improving battery performance and service life. In the ceramic and refractory industry, they handle high-hardness raw material grinding to enhance product density and strength. They are also widely used in electronic ceramics, precision metallurgy, paint and ink, and pharmaceutical industries, adapting to both wet and dry grinding environments to meet diversified industrial grinding needs.
Their high Vickers hardness of 11.0-12.0 GPa and dense sintered structure provide strong wear resistance and impact resistance, enabling stable grinding of various hard materials without damage.
Their grinding efficiency is 30%-40% higher than ordinary alumina ceramic balls, thanks to high density and smooth surface that optimize grinding force and speed.
Yes, they have excellent chemical stability, resisting most acids, alkalis and organic solvents, and will not react with most grinding materials to ensure product purity.
The available size range spans from 0.5mm to 30mm, accommodating fine to coarse industrial milling specifications.
They feature an ultra-low wear rate of ≤0.008% per 1000 hours and a high ZrO2 purity of ≥95%, ensuring optimal stability and minimal media loss.
These balls are produced from premium Yttrium Stabilized Zirconium Oxide (Y-TZP) with a bulk density of 6.0-6.1 g/cm³.
