Applications
Zirconia ceramic beads are widely used in the ultra-fine grinding and dispersion of materials across industries: metal materials, non-metallic minerals (including gold ore), oil paint, inks, dyes, titanium dioxide, pesticides and magnetic materials. Their high density delivers faster grinding under identical conditions.
Why Choose HuaTong Polishing Media ZIRC
- Higher grinding efficiency — specific gravity about 1.6× ordinary zirconia beads.
- Longer service life — excellent roundness, smooth surface and very low attrition (0.1%).
- Lower equipment wear — reduces machine and mill lining wear compared with other grinding media.
Note: price is relatively higher than conventional ceramic media, but the efficiency and service life deliver strong ROI in high-value fine grinding.
Frequently Asked Questions
What does TZP zirconia bead mean?
TZP stands for tetragonal zirconia polycrystal, stabilized with yttrium. It gives the beads exceptional toughness, strength and wear resistance, with a specific gravity around 1.6 times that of ordinary zirconia beads.
Which mills are ZIRC beads suitable for?
These beads suit bead mills, stirred mills and other ultra-fine grinding and dispersion equipment across paint, ink, pigment, mineral and magnetic-material processing.
What bead size do I need for fine grinding?
The right size depends on your feed particle size and target fineness — smaller beads (0.4–1.0 mm) suit nano/fine grinding, larger beads suit coarser milling. HuaTong can recommend a size based on your process.
