Product Details

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
