Zirconia Grinding Ball Detailed Introduction
Chemshun TZP beads have high fracture toughness and nice impact resistant that causes no break under high speed impact
The TZP beads have 30-50 times higher wear-resistance as glass beads, 5times higher as Zirconium Silicate beads and 6-8 times higher as Al2O3 beads
Because of the high density and excellent grinding efficiency of our TZP beads , they greatly apply to grinding and dispersing high viscosity materials
