Product Description

wear resitant zirconia ceramic beads for grinding and polishing

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.

1.High strength, high fracture toughness, wear resistant, high hardness, corrosion reistance, ultra smooth surface. easy clean, reduce the intermal friction between the beads and improve the material flow efficiency.

2. Good spherical degree

3. Lower costs for its long using life.

Application: Material for grinding and dispersed, structural ceramics, electronic ceramics, refractory ceramics, magnetic material, zirconia silicate, food, medical, high grade color glaze and mechinical equipments, etc.

Available size: Sphere(Diameter):0.6mm,0.8mm,1mm,1.2mm,1.4mm,2.0mm,3.0mm, 5mm, 6.5mm,7.0mm,,8.5mm,10mm,12mm,15mm,20mm,25mm,30mm etc

Cylinder(Dimater):3x3mm,5x5mm,7x7mm,10x10mm,12.7x12.7mm,15x15mm,20x20mm etc

Advantages:

Compareed with the trational grinding medium, such as alumina balls, zirconium silicate balls, steel ball and glss beads, the zirconia grinding medium(Y-TZP grinding medium) has high density, high hardness and high fracture toughness factures, which provide it higher grinding efficiency than the traditional grinding medium, it can protect materials from pollution and guard against chemical corrosion.
