YSZ Grinding Media

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.

Zirconium Silicate Grinding Media

High Grinding Efficiency

Grinding and dispersing efficiency are significantly improved owing to the beads’ possession of higher kinetic energy created by its big specific gravity. In the course of grinding, as a result, outlet speed and flow rate increase while circulation time as well as required grinding time drops. You will have both finished products in desired fineness and improved productivity.

High density, high tenacity, impact-resistance and low wear.

The advantage of its superior wear-resistance is highlighted especially in grinding of products with high precision and high solid content.

Highly stable chemical properties, corrosion-resistance, make it applicable as both acid and alkaline media.

Smooth surface makes cleaning an easy work.

Far less wear will take place to mechanical equipment.
