zirconia balls special for grinding machine best grinding medium used in bearing seals
product name:zirconia balls
model:HY-YHG
Product Features :
At room temperature, it has the advantages of high strength and high toughness, high density, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic, electrical insulation, and thermal expansion coefficient close to steel. The strength and hardness of zirconia ceramic balls are almost unchanged at 600 °C. Yttrium oxide was used as stabilizer, which was made by special molding process and high temperature baking phase-fixing process.
Uses :
It is especially suitable for vertical stirring mill, horizontal rolling ball mill, vibration mill and various high-speed rod-pin sand mills. Wet and dry ultra-fine dispersion and grinding of various slurry and powder that require rejection of cross-contamination. The application areas are as follows :
1, wear-resistant, corrosion-resistant products : paint, ink, paint, paper, solar cells, non-metallic minerals
2, high strength, high toughness products : magnetic materials, piezoelectric ceramics, dielectric ceramics, electronic materials
3, to prevent pollution : medicine, food, cosmetics, pigments
Ceramics : electronic ceramics, refractory ceramics, structural ceramics
