Product Description

Size 30mm Zirconia balls for non-metallic ore coarse grinding in mixing mill


  • Discription

Zirconia balls belong to a class of grinding beads, with a density of 6.0, a bulk density of 3.2, a content of about 95% zirconium oxide, and a content of 4.8% yttrium. They are also called 95 yttrium stabilized zirconia balls.
Zirconia balls can be used as grinding and grinding media in stirring mills, sand mills, and ball mills.

  • Features


High grinding efficiency:

Due to the high density of zirconia balls 6.00g/cm3, they have greater grinding kinetic energy at the same movement speed, and the grinding efficiency is 2-3 times higher than that of ordinary ceramic beads. You can get a more ideal effect.


Good Impact resistance and low abrasion:

Due to the high content of ZrO2, the zirconium beads have the advantages of high density, high toughness, low abrasion, no broken balls, peeling, etc., and it has little dispersal and pollution to the abrasive.

The abrasion is 4-10 times lower than ordinary ceramic beads.


Good thermal stability

Good wear resistance in high temperature and corrosion resistance, high rigidity, non-magnetic conductivity, and electrical insulation. When the zirconia ceramic ball is at 600℃, its strength and hardness are almost unchanged.



  • Application
