Yttrium Stabilized Zirconium Oxide Grinding Balls
Reference:
Manufacturer: Across International
- The industry standard for highly cost-effective, low wear and long lifetime: YSZ is among the most durable, chemically resistant and efficient media for use as a milling/grinding material for ceramic materials, wet grinding, and applications that seek to minimize contamination. Due to its ultra-low wear loss, its operational cost can be lower.
- High specific gravity, and thus high efficiency, saving processing time.
- Highly resistant to acids, solvents, mild and moderate bases.
- Highly polished, smooth, easy to clean, low abrasion to the equipment.
