  • TZ38

  • TITAN

Product Overview

  • Al₂O₃ + ZrO₂: ≥ 92%

  • Density: ≥ 3.75 g/cm³

  • Vickers Hardness: ≥ 12 GPa

  • Quick Mill Wear Rate: ≤ 0.7 g/kg·h

TZ38 is engineered for processes that require higher density and better impact resistance than standard alumina balls, offering improved grinding efficiency and longer service life.


Product Advantages

  1. Higher Density (≥ 3.75 g/cm³): Generates stronger grinding force and better output in ball mills.

  2. Improved Toughness: Zirconia reinforcement prevents cracking under heavy loads.

  3. Lower Wear Rate: ≤0.7 g/kg·h, outperforming traditional alumina media.

  4. High Hardness (≥12 GPa): Maintains stable shape and grinding performance even in long cycles.


Product Features

  • ZTA structure offering both hardness and impact strength.

  • Suitable for both wet and dry grinding.

  • Provides stable particle size distribution.

  • Ideal for high-demand grinding processes in mining, ceramics, pigments, chemicals, and nano-materials.


Benefits of Using TZ38

  • Increased grinding efficiency due to higher density.

  • Lower media consumption and reduced operational cost.

  • More stable production with fewer unplanned shutdowns.
