Product Description

ZTA Composite Zirconia Toughened Alumina Grinding Balls Pebbles Impact Resistance

Advanced Material for Superior Impact Resistance

Zirconia-Toughened Alumina (ZTA) composite balls represent a breakthrough in grinding media technology, combining alumina's hardness with zirconia's fracture toughness for exceptional impact resistance and wear performance.

Key Properties of ZTA Composite Balls

Increased Fracture Toughness: Superior resistance to impact loading compared to standard alumina materials
Excellent Wear Resistance: Smooth microstructure provides 2-15 times better wear resistance than high alumina media
Thermal Stability: Efficient heat dissipation for high-temperature applications
Chemical Inertness: Resistant to acids, alkalis, and corrosive environments

Key Advantages

30% lower wear than standard 92% alumina grade
2-5x longer lifespan compared to steel in abrasive applications
Superior hardness to zirconia for fine grinding applications
Cost-effective alternative to pure zirconia media

Industrial Applications

Mining & Mineral Processing: Improved grinding efficiency with reduced contamination
Pharmaceuticals: FDA-compliant, no endotoxin release
Battery Manufacturing: Prevents metal contamination in cathode materials
Paints & Coatings: Maintains color purity with no metal leaching
Medical & Aerospace: Biocompatible and thermally stable for demanding applications

Packaging Information

Standard packaging includes 25KG woven bags, with 1000KG-1250KG per pallet shrink wrapped for secure transportation.

Frequently Asked Questions

What are ZTA composite balls made of?

They are composed of aluminium oxide (Al₂O₃) reinforced with zirconia (ZrO₂), creating a high-performance ceramic material with enhanced toughness.

What are the key advantages of ZTA balls?

ZTA balls offer superior impact resistance, excellent wear properties, chemical stability, and thermal resistance up to 1600°C.

Why choose ZTA over other grinding media?

ZTA provides the optimal balance between cost and performance, offering zirconia-like toughness at a more economical price point.

What customization options are available?

We offer various sizes (1mm-100mm), zirconia content adjustments, and specialized grades to meet specific application requirements.
