Product Details

Zirconia porcelain ball is a wide range of programs of inorganic non-metallic grinding medium, particularly used in grinding and dispersion of most important regions, our organisation especially produces grinding with zirconium balls, mainly concerned inside the sand mill internal, dispersion is especially involved in excessive-speed mixing mill inner. zirconia beads are made from micron-degree and sub-nano zirconia and yttrium oxide as uncooked substances thru superior generation to make diverse technical indicators and performance signs to reach the global fashionable degree. in particular used in extremely-excellent grinding materials that require "0 pollutants" and high viscosity and excessive hardness materials.
