These ZrO2 grinding balls cover diverse high-precision industrial milling fields. In electronic materials, they are ideal for grinding dielectric, piezoelectric and magnetic materials without introducing metal impurities. In coating, ink and pigment industries, they achieve ultra-fine dispersion to improve product fineness and gloss. They also apply to fine ceramics, new energy battery materials, pharmaceutical raw materials and chemical fillers, perfectly matching high-standard fine processing requirements of various industrial materials.
Featuring high density and uniform sphericity, ZrO2 grinding balls provide strong shear and impact force to shorten grinding cycles and boost production efficiency. With excellent acid and alkali corrosion resistance, they adapt to various complex grinding environments. Their ultra-low wear rate effectively avoids media pollution and reduces equipment loss. Compared with glass and alumina balls, their service life is 5-50 times longer, greatly lowering overall industrial production costs.
They fit most industrial ball mills, sand mills and planetary grinding machines, compatible with both wet and dry fine grinding modes for versatile industrial use.
Select small sizes (0.05-3mm) for ultra-fine grinding and large sizes (3-20mm) for coarse grinding and material pre-crushing based on target fineness.
It features higher hardness, zero metal contamination and longer service life, ensuring stable quality of high-end industrial fine-processed materials.
Key specifications include ZrO2 purity ≥94.5%, high density of 6.0-6.1 g/cm³, Vickers hardness ≥1200 HV, available sizes ranging from 0.05mm to 20mm, and an ultra-low wear rate of ≤0.01‰/24h.
Compared with traditional glass and alumina balls, their service life is 5-50 times longer. Combined with an ultra-low wear rate and high efficiency, they significantly reduce media replacement costs and equipment wear.
