Product Details

Zirconia porcelain ball Zirconia porcelain ball is a wide range of applications of inorganic non-metallic grinding medium, mainly used in grinding and dispersion of two major areas, our company mainly produces grinding with zirconium balls, mainly involved in the sand mill inside, dispersion is mainly involved in high-speed mixing mill inside. Zirconia beads are made of micron-level and sub-nano zirconia and yttrium oxide as raw materials through advanced technology to make various technical indicators and performance indicators to reach the international standard level. Mainly used in ultra-fine grinding materials that require "zero pollution" and high viscosity and high hardness materials.
