Product Description:
Zirconia Grinding Beads
Zirconia grinding beads is also called Zirconia grinding ball or Zirconia ceramic ball or Zirconium bead or ultrafine grinding media. It owns gloss of pearl and smooth surface and is the best ball among all grinding media.
Application:
1. Particularly suitable for vertical stirring mills, horizontal roller ball mills, vibrating mills and various high linear, speed pin- type sand mills.
2. For wet or dry ultrafine dispersion and grinding of pastes and powders without contamination.
3. Perfect grinding media with good flatness, smooth surface, bright,high density and high strength.
4. Wear and corrosion resistant product: coating, textile, pigment, dyeing.
5. High strength, high tenacity product: magnetic material, piezoelectric ceramics, dielectric ceramics.
6. Pollution prevention: medicine, food, cosmetics.
7. Ceramics: electronic ceramics, refractory ceramics, structural ceramics.
Features:
high hardness
good wear resistance
high mechanical strength
low wear loss
corrosion resistance
non-conducted, low thermal conduction
high thermal expansion rate
non-greased and self lubrication
light weight with low density, decrease in centrifugal load
