Pls first check the technical specification for our high alumina grinding media ball as the following:

1) 92% alumina grinding ball

  • Al2O3: 92% Min.
  • Fe2O3: 0.25% Max.
  • Mohs Hardness: 9
  • Water absorption: 0.02% Max.
  • Density: 3.60 g/cm3 Min.
  • EWT: 0.15 Max.

2) 95% alumina grinding ball

  • Al2O3: 95% Min.
  • Fe2O3: 0.20% Max.
  • Mohs Hardness: 9
  • Water absorption: 0.02% Max.
  • Density: 3.65 g/cm3 Min.
  • EWT: 0.10 Max.

If your grinding work mode is batch grinding, then 92% alumina grinding ball is O.K., if your grinding work mode is continuous grinding, then 95% alumina grinding ball is most recommended.
