BPA High Purity Alumina Beads
Product Description
High Purity Alumina Beads
Feature
Excellent abrasion resistance
Abrasion resistance is higher than other zirconia beads.
High purity
The purity of the alumina beads is 99.99% or more. Compared with alumina, no contamination occurs during grinding.
Excellent corrosion resistance
It shows excellent corrosion resistance against acid and alkali. It works well in the warm water.
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.
Application
