Zirconium Silicate Bead

Characteristics:
1. Good round sphere, smooth surface, pearl-like shine.
2. Good tenacity, impact-endurable, no break under high speed impact.
3. 30-50 times better than glass bead in terms of wearability.
4. Higher density than any other grinding bead brings higher grinding efficiency, thus allowing higher solid proportion or increased material flow.
