Zirconia Toughened Alumina Beads K-400 | High-Density (≥4.00 g/cm³) Grinding Media for Minerals & Coatings
Our K-400 Zirconia Toughened Alumina (ZTA) Beads represent the pinnacle of grinding media technology for high-speed sand mills and agitator mills. Engineered with an optimized microcrystalline structure and superior density, these composite ceramic beads deliver exceptional grinding efficiency and wear resistance for the most demanding fine-grinding applications.
Key Features & Performance Benefits
Advanced Microstructure: Uniform internal crystalline phase with fine grain boundaries creates optimal structural integrity
Precision Sphericity: >95% roundness with controlled size distribution ensures consistent grinding performance
High-Density Design: ≥4.00 g/cm³ density provides greater impact energy for faster particle size reduction
Zero Void Structure: Complete absence of hollow beads minimizes wear and extends service life
Superior Surface Finish: Smooth, polished surface reduces contamination and improves flow characteristics
