Yttria Stabilized Zirconia Grinding Beads

  • Component:94.8%ZrO2,5.2%Y2O3
  • Filled Density:3.5(φ5mm)
  • Density:>6.00 g/cm3
  • Hardness:>1200
  • Yttria Stabilized Zirconia Grinding Beads
■Applications
Technical principle :
Yuli Yttria stabilized zirconia grinding beads are manufactured by special moulding technics and stabilized by Yttria.

Yuli Yttria stabilized zirconia grinding beads are high-strength, high density, abrasive resistance-well, anti-high temp. Anti-corrosion products. Its specific gravity is 1.6 times higher than zirconia silicate ceramic grinding beads, Yttria stabilized zirconia grinding beads are more efficiency on milling. It is roundness-well and more smooth, so it is less-abrasion than other grinding mediums for equipments. the abrasion for itself is only half of zirconia silicate grinding beads due to its high strength.

 

Applications:
Yuli Yttria stabilized zirconia grinding beads also named zirconia ball, zirconia ceramic ball, zirconia beads, fine grinding medium, zirconia grinding beads etc.
Yuli Yttria stabilized zirconia grinding beads are very suitable for vertical mixing mill, horizonal ball mill,vibromill and sand mill. It is also be used in the areas shown as below:
anti-abrasive products: coating, spinning, pigment, dyeing.
High strength products: magnetic products, piezoelectric ceramics.
De-pollution products: medicine, food, cosmetics.
Ceramic products : electronic ceramic, refractory ceramic, structural ceramics.
