Property
1.High specific density : the specific density is 1.6 times more than ordinary zirconia beads.
2.Preventing material from contamination because of its extreme low wear rate.
3.High grinding efficiency.
4.Lower total cost with longer using life.
Recommendations For Grinding Applications
-
In high energy mills, like pin-mills.
For water-based milling products with low viscosity, low solids - like ink-jet.
In the food industry, for pharmaceutical products and cosmetics.
