Ball Zirconia ZirconiaCeramic Beads Polishing Tumbling Media Alumina Oxide Ceramic Ball Ceramic Grinding Beads Zirconia Ceramic
Zirconium products are with high strength, high fracture toughness, a large proportion of the wear-resistant, ppm wear grade, high hardness, corrosion resistance, ultra-smooth surface features and etc.
TZP grinding media with very low wear and high fracture toughness is widely applicable to various grinding and dispersion conditions, and to ensure the product's purity and life.
Applications
Especially suitable for vertical mixing mill, horizontal rolling ball mill, vibration mill and all kinds of high line speed bar pin sanding machine;For a variety of requirements to refuse cross-contamination of slurry and powder for wet and dry method of ultra-fine dispersion and grinding
1. Wear-resistant and corrosion-resistant products: coatings, textiles, pigments, printing and dyeing
2. High-strength and high-toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics
3. Prevention of pollution: medicine, food and cosmetics
4. Ceramics: electronic ceramics, fire-resistant ceramics, structural ceramics
