65 Zirconia Beads Grinding Media Zirconium Silicate Beads 1.8-2.0mm
2.0-2.2mm for Paint & Coating
1. Product Description of 65 Zirconia Beads
Zirconium silicate beads contain 65% ZrO2,so it is also called as
65 zirconia beads. It is made by special
baking and phasing process under high temperature,and there are no
pores and cavities in the ball.
Zirconium silicate beads has medium density and hardness, suitable
for dispersion and grinding of medium
and low viscosity slurry, which can match most sand mills.

3. Main Applications of 65 Zirconium Silicate Beads
suitable for ultra-fine grinding of calcium carbonate, kaolin,
titanium dioxide, coatings, magnetic coating,
paints, inks,metal ores etc.
4. Main Features of 65 Zirconia Beads
Uniform and dense crystal structure,which ensures the consistent
fineness of grinding materials
Good toughness and impact resistance,which is little damage to
grinding equipments
Low grinding cost compared with 95 zirconia beads
5. Applicable Equipments:
Vertical sand mill, horizontal sand mill, basket sand mill, ball
mill, vibration mill etc
6. How and when to refuel the grinding beads?
It is known that there is natural loss of grinding beads in
grinding process,then the particle size of beads
will become smaller and smaller. In order to maintain a uniform
filling amount and avoid fine beads blocking
or entering the separation device, the broken beads shall be
screened out and a certain amount of grinding
beads shall be supplemented according to the service life of the
grinding machine and the conditions of its
own process. It is generally suggested to do the above work after
100-200 working hours.
