YSZ Grinding Media Cylinders zirconia bead/ball

YSZ (Yttria Stabilized Zirconia)

grinding media feature high density, toughness and super hardness, enabling to achieve superior grinding efficiencies compared with other conventional grinding media such as Alumina and Agate.

The high wear-resistant YSZ grinding media effectively eliminate product contamination and lengthen service life of the grinder. These special features make YSZ grinding media especially suitable for sensitive products and critical applications. YSZ grinding media are widely used for high viscosity, wet grinding and dispersion.

YSZ Grinding Media Cylinders (Zirconia Beads/Balls) are high-performance grinding media made from Yttria-Stabilized Zirconia (YSZ), a ceramic material known for its exceptional hardness, wear resistance, and chemical stability. These grinding media are widely used in industries such as paints and coatings, pharmaceuticals, ceramics, electronics, and minerals processing for fine grinding, dispersion, and mixing applications.

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.
