Quick Details

 Zirconia Microsphere Grinding Beads are high-performance grinding media used in ball millsstirred mills, and bead mills for fine grinding, dispersion, and homogenization of materials. Made from yttria-stabilized zirconia (YSZ), these beads are known for their exceptional hardness, wear resistance, and chemical stability. They are widely used in industries such as paints and coatingspharmaceuticalsceramicselectronics, and minerals processing to achieve ultra-fine particle sizes and uniform dispersion.


1. Main Advantage of the zirconia bead/ball

  • Excellent wear resistance, Weight loss of ball lee of 4ppm,

  • High density, grinding efficiency,

  • No impurity, keep the material high degree of purity.

2. Main Use of the zirconia bead/ball

  • Electronic material (Such as BaTiO3,BaCO3), Magnetic bands superfine grinding,

  • Paint,pigment, Coatings dispesing and superfine grinding,

  • Ceramic glaze(zirconia sand) superfine grinding,

  • Medication, Cosmetic dispersing and superfine grinding.
