Product Description
Zirconium Oxide Beads
The content of zirconia in the beads is approximately 95% so it is usually called “95 Zirconium” or “Pure zirconia beads”. With the rare earth yttrium oxide as stabilizer and the raw material of high whiteness and fineness, there will be no pollution to the grinding material.
The zirconium oxide bears are used for superfine grinding and dispersing of zero pollution, high viscosity, high hardness and so on. It is applied to the equipment like horizontal sand mills, vertical sand mills, basket mills, ball mills and attritors.
