Zirconia Toughened Alumina Beads K-380 | High-Density Grinding Media
Product Description
Our K-380 Zirconia Toughened Alumina (ZTA) Beads are high-performance composite ceramic grinding media engineered for high-speed and high-energy milling processes, such as agitator and sand mills. They deliver exceptional wear resistance and grinding efficiency for a wide range of hard-to-grind materials.
Key Features & Benefits
Superior Hardness & Wear Resistance: With a Vickers Hardness of 1350 kg/mm², the K-380 beads significantly reduce media consumption and prevent product contamination, ensuring a longer service life and lower operational costs.
High Density & Impact Force: A density of ≥3.70 g/cm³ provides greater impact energy per bead, leading to faster particle size reduction and improved milling efficiency, especially for viscous slurries.
Precision Engineering & Structural Integrity: Featuring high sphericity (>95%) and a uniform, void-free internal crystalline structure, these beads guarantee consistent grinding results, minimize slurry viscosity increase, and offer exceptional fracture toughness.
Proven Chemical Inertness: Highly resistant to acids and alkalis, they are ideal for demanding chemical environments in industries like paints, inks, and ceramics, ensuring product purity.
