95 Yttrium Stabilized Zirconia Beads Grinding Media 1.8-2.0mm
2.0-2.2mm for High Viscosity Slurry
1. Product Description of 95 Zirconia Beads
95 yttrium stabilized zirconia beads is also called as 95 zirconia
beads or TZP(tetragonal zirconia polycrystallite)
zirconia beads.It selects the yttrium oxide as stabilizer and produces through
special molding process and
high-temperature baking and phasing process,its strength and
hardness are almost unchanged under 600 ℃.
95 zirconia beads has pearl like luster and smooth spherical
surface ,mainly used for superfine dispersion
and grinding of various slurry and powder materials that are
required to zero contamination by wet and dry
grinding methods.

3. Main Features of 95 zirconia Beads
High grinding efficiency
The specific gravity of 95 yttrium stabilized TZP zirconia beads is
1.6 times as the one of 65 zirconia beads,
which will achieve higher grinding efficiency under same grinding
conditions.
Good fluidity:
95 zirconia beads has good roundness, smooth surface and little
damage to the equipment.
High impact resistance and low-wear rate
95 zirconia beads beads has good toughness, it will not be cracked
or peeled off in grinding machines with
high-speed and high concentration, its wear rate is only half of
that of zirconium silicate beads.
Zero pollution to the grinding materials
There is no pollution to the grinding material, which ensures the
purity of the grinding materials
High price/performance ratio
95 zirconia beads will finally reduce the overall grinding cost in
abrasion rate, power consumption, labor wage
and equipment loss etc,it is one high efficiency grinding media in
the long term.
4. Main Applications of 95 Zirconia Beads
mainly used for ultra-fine grinding and dispersion of high-purity
ceramic materials such as electronic ceramics,
magnetic materials, aluminum oxide powder, quartz, zirconium
silicate and titanium dioxide, as well as food,
cosmetics, paints, coatings, pigments and inks.
5.Applicable equipment:
vertical mixing mill, horizontal rolling ball mill, vibration mill
and various high-speed rod pin sand mills
