Bynames: Zirconia ball, zirconia ceramic ball, zirconia bead, ultrafine grinding media, zirconia microball, zirconia grinding ball

Pearl-like luster and a smooth working sphere. It is the top class of grinding media

Applications: Particularly suitable for vertical stirring mills, horizontal roller ball mills, vibrating mills and various high linear speed pin-type sand mills, for wet or dry ultrafine dispersion and grinding of pastes and powders requiring to refuse cross contamination. Its application includes:
1.Wear and corrosion resistant product: coating, textile, pigment, dyeing
2.High strength, high tenacity product: magnetic material, piezoelectric ceramics, dielectric ceramics
3.Pollution prevention: medicine, food, cosmetics
4.Ceramics: electronic ceramics, refractory ceramics, structural ceramics

Features: High strength, high tenacity, high density; sound wear resistance; heat and corrosion resistance; high rigidity; non-magnetic conducting; electric insulation and thermal expansion coefficient close to that of steel. The alumina ceramic ball is subject to little strength and hardness variation even under 600℃. It is baked under high temperature on fixed phase basis by a special shaping process using yttria as the stabilizer.
1.High grinding efficiency: Yt-stabilized TZP zirconia ceramic microball has a specific gravity 1.6 times that of common zirconia beads and ensures higher grinding efficiency under the same conditions
2.Sound fluidity: The product provides sound circular integrity, is smooth on the surface and causes lower abrasion to equipment than any other grinding medium
3.Impact resistant, low abrasion: TZP zirconia ceramic microball has sound tenacity, does not crack or strip in high speed/high concentration machines, with abrasion only 1/2 that of zirconium silicate beads
4.Low service cost: Choosing this product will undoubtedly bring down our cost on media abrasion, power consumption, labor and equipment, and significantly improve your product quality
