Zirconia Round Beads Grinding Media Zirconia Beads Ceramic Balls Grinding Media Ball
Description
Zirconia beads have been successfully used in the ultrafine grinding and dispersion of heavy calcium carbonate, inks, coatings, MLCC, ceramic inks and other products at home and abroad.
The products have passed international BV certification and have been successfully exported to Europe, the United States, Germany, Japan, Southeast Asia and other countries.
Yttrium stabilized zirconia beads Properties: alias zirconia balls, 95 zirconia ceramic balls, zirconia beads, ultra-fine grinding media, zirconia beads, zirconia grinding balls.
With pearl-like luster and smooth working spherical surface, dense internal structure, ultra-high specific gravity of 6.0, strong pressure resistance and ultra-high wear resistance, it is in the grinding medium. However, this product has higher requirements for the hardness of the memory material used in the inner cylinder of the grinding machine.
Application:
Yttrium stabilized zirconia beads Uses: especially suitable for horizontal sand mills, high-speed stirring mills, vibration mills, ultra-fine mills and various high-speed pin sand mills, etc.; for various requirements to refuse cross-contamination slurry It can be used for wet and dry ultra-fine dispersion and grinding with powder. The application areas are as follows:
1. Wear-resistant and corrosion-resistant products: inks (including ceramic inks), high-end pigments, high-end paints, coatings.
2. High-strength, high-toughness products: magnetic materials, electronic components (ceramic variable vessels, thermistors, etc.), electronic materials (liquid crystal display color paste, plasma display glass paste, semiconductor polishing slurry, etc.).
3. Prevent pollution: medicine, food and food additives, cosmetics.
4. Ceramics: electronic ceramics, refractory ceramics, structural ceramics.
Appearance: With pearl-like luster and smooth working spherical surface, it is the best in grinding media.
Features: High strength and toughness, high density, good wear resistance, high temperature and corrosion resistance, high rigidity, high toughness at room temperature
Magnetic conductivity, electrical insulation, thermal expansion coefficient close to steel and other advantages. The strength and hardness of the zirconia ceramic ball at 600℃
Almost unchanged. Using yttrium oxide as a stabilizer, it is made by a special molding process and a high-temperature firing and phasing process.
1. High grinding efficiency: the specific gravity of yttrium stabilized TZP zirconia ceramic beads is 1.6 times that of ordinary zirconia beads, under the same conditions
Has a higher grinding efficiency.
2. Good fluidity: The product has good roundness and smooth surface, and the wear on the equipment is lower than other grinding media.
3. Impact resistance and low abrasion: TZP zirconia ceramic beads have good toughness and will not crack or open in high-speed, high-concentration machines
Peeling and abrasion are only 2/1 of the zirconium silicate beads.
4. Low cost of use: Choosing this product will definitely bring you a reduction in comprehensive costs such as media wear, power consumption, labor, and equipment, and greatly improve product quality.
