Zirconia Ceramic Grinding Media

80% zirconia beads are shaped by special dropping & granulated from the ultra fine zirconium dioxide and alumina powder. The consistent micro poly-crystal benefits high compressive strength and wear resistance of beads.

Product Details

Product Introduction:

80% zirconia beads are shaped by special dropping & granulated from the ultra fine zirconium dioxide and alumina powder. The consistent micro poly-crystal benefits high compressive strength and wear resistance of beads. The perfect sphericity and middle to high gravity increase the grinding efficiency. It is an economic replacement of YSZ bead.

Features:

1. Good roundness, smooth surface and no air hole;

2. The specific gravity and hardness are closed to the Y-TZP beads;

3. Higher wear rate than Y-TZP, but lower unit cost;

4. Matching mills: general stirred mills with disc and pins.

Applications:

1.	Suitability for dispersing the solvent or water base slurries in disc and pin type mills;
2.	Coating and paints: prime and top coating of auto, coiling coating, paper coating, emulsion paint and marine paint;
3.	Pigments: TiO₂, CaCO₃ and ceramic glazing.
