Zirconia grinding beads are made of micron and nano zirconia powder and yttrium oxide as raw materials. They have characteristics of high strength, high tou-ghness, high density, high hardness, and excellent wear resistance and corrosion resistance. And Zirconia grinding beads’ high density and high impact force bring high grinding efficiency, which can reduce the time required for grinding. Therefore they are very suitable for the field of wet grinding.

Zirconia grinding beads are mainly applied for ultra-fine grinding and dispersion of materials which require "zero pollution", high viscosity and high hardness, such as electronic ceramics, magnetic materials, zirconia, silicon oxide, zirconium silicate, titanium dioxide, medicine and food, pigments, dyes, inks and special chemical industries.

Zirconia grinding beads is the common consumables of wet sand mill. Operaters are supposed to operate correctly to avoid the breakage of zirconia grinding beads and prolong the service life of grinding medium and contact parts of sand mill as far as possible. There are the following precautions:
