High Purity Alumina Grinding Ball

BPA

High Purity Alumina Grinding Beads/99.5% Alumina Balls

Product Details

Feature

1.Excellent Abrasion Resistance

Abrasion resistance is higher than the zirconia beads. when the high hardness ceramics is ground,

2.High Purity

The purity of the alumina beads is 99%or more. When grinding, no contamination other than alumina.

3.Excellent Corrosion Resistance

It is excellent in corrosion resistance to the acid and the alkali.

No performance deterioration in the warm water.

4.Energy Saving of Grinding and Dispersion

The density of alumina is 2/3 of the zirconia bead, and the filling weight to the mill is 2/3.

In addition, the consumption energy when grinding can be decreased.
