65 Zirconia Grinding Media Zirconium Silicate Beads 1.8-2.0mm
2.0-2.2mm for Paint
1. Product Description of Zirconium Silicate Beads(65 Zirconia
Beads)
Zirconium silicate beads selects the high-purity ultra-fine
zirconium silicate powder as raw materials, then
made into different size by special sintering process. Zirconium
silicate beads contains 65% ZrO2, also
called as 65 zirconia beads.
It has uniform and dense microcrystal structure,which is one
cost-effective grinding media compared with
95 zirconia beads.

High price/performance ratio;
little damage to the grinding equipments;
Zero contamination to the treated materials.
4. Main Applications of 65 Zirconia Beads
Mostly used in the grinding and dispersion of calcium carbonate,
kaolin, titanium dioxide, pesticides,
inks, paints and coatings.
5. The difference between Zirconium Silicate Beads and Ceramic
Beads Blasting Media
Firstly,produced by different process: Zirconium silicate beads is
made by sintering process,while
ceramic beads is produced by melting process.
Secondly,different chemical composition: Zirconium Silicate Beads
contains Min 65% ZrO2 and 25-30%
SiO2,while Ceramic beads contains 60-66% ZrO2,7-13% Al2O3 and 25-30% SiO2.
Thirdly,different particle size: Zirconium silicate beads has wide
size from 0.2mm to 10mm,while ceramic
beads has narrow size from B20(0.600-0.850mm) to
B505(0.010-0.030mm).
Fourthly,different applications: Zirconium silicate beads is one
grinding media,equipped with sand mills,
while ceramic beads is one popular blasting media,matched with
blasting machines.
