Factory Wholesale Price Ceramic Balls Zirconia Beads Grinding Beads
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.
Yttrium stabilized zirconia beads Properties: alias zirconia balls,
95 zirconia ceramic balls, zirconia beads, ultra-fine grinding
media, zirconia beads, zirconia grinding balls.
It has a pearl-like luster and a smooth working spherical surface,
a compact internal structure, an ultra-high specific gravity of
6.0, strong pressure resistance and ultra-high wear resistance, and
is in a grinding medium. However, this product has higher
requirements for the hardness of the memory material used in the
inner cylinder of the grinder.
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 and corrosion resistant product: coating, textile, pigment,
dyeing.
2. High strength, high tenacity product: magnetic material,
piezoelectric ceramics, dielectric ceramics.
3. Pollution prevention: medicine, food, cosmetics.
4. Ceramics: electronic ceramics, refractory ceramics, structural
ceramics.
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.
Characteristics of Yttrium Stabilized Zirconia Beads:
1. High grinding efficiency: The specific gravity of
yttrium-stabilized TZP zirconia ceramic beads is 1.6 times that of
zirconium silicate beads and 3 times that of glass beads. It has a
higher grinding efficiency under the same conditions.
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: YZB zirconia ceramic beads
have good toughness, and will not crack or peel in high-speed,
high-concentration machines. The wear resistance is 50 times that
of glass beads and about 5 times that of 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.
