95 Yttrium stabilized Zirconia Beads Grinding Media for High
viscosity& High hardness materials
1. Product Description of 95 Zirconia Beads
The crystal structure of 95 zirconia beads is mostly Tetragonal
Zirconium Polycrystal, so it is also called
as "TZP" zirconia beads, it selects the micron and sub-nano
zirconium oxide and yttrium oxide as raw
materials, then sintered under high temperature, finally made into
different size by special technology.
It is mainly used for the ultra-fine grinding and dispersion of
high-viscosity and high-hardness materials
which requires zero pollution.

Ultrafine grinding and dispersion of medicine and cosmetics
5. Precautions for using 95 zirconia beads:
Select the suitable zirconia beads according to the viscosity,
hardness, dispersed particle size and grinding
requirements of the grinding material;
Clean the inner wall of the grinder barrel before grinding
Put the grinding material into the grinder firstly, then put the
right amount of zirconium beads.
Gradually add the zirconia beads after the grinder is running
normally. The filling volume is generally 70%-85%
of the internal volume of the grinder barrel;
Do not run the grinder for a long time under the condition of lack
of grinding material, otherwise the grinder is
easy to be damaged;
Suggest to refuel the new zirconium beads appropriately to ensure
the quality and efficiency of the grinding after
the grinder has running for a long time
6. How to distinguish the normal abrasion and broken beads?
Generally speaking, the zirconia beads will become smaller when
working for a period ,but still smooth in the
surface without edges and corners , which should be the wear of
normal beads;
On the contrary, if there are angular, flake shaped beads in the
beads, it should be broken beads.
