Specifications
* Zirconia mill ball* Big density
* High strength
* Good corrosion resistance
Zirconia Mill Ball:
This product is particularly suitable for vertical stirred mill, horizontal rolling mill, vibration mill, and various high-wire-speed sanding stick pins, etc.; the requirements of the refusal to cross-contamination of the slurry and powder for wet, dry dispersion and the ultra-fine grinding.
Features:
1.Wearing a very low (ppm) the amount of materials to prevent pollution
2.High grinding efficiency
3.Extremely long life, low cost integrated
4.For high viscosity, wet grinding and dispersion of occasions
Applications:
1.Wear-resistant, corrosion-resistant products: paints, textiles, paints, printing and dyeing
2.High strength, high toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics
3.To prevent pollution: medicine, food, cosmetics
4.Ceramics: Electronic ceramics, refractory ceramics, structural ceramics
