About 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.
