Product Description
High Alumina Grinding Ball Overview
High alumina grinding balls are engineered for efficient material grinding applications, specifically designed for use in ball mills and batch ball mills. These grinding media balls feature a composition of 99+% alpha alumina with maximum 0.2wt% SiO₂ content, making them ideal for demanding industrial grinding processes.
Key Product Features
- High density of 3.9 g/cm³ for superior grinding efficiency
- 99+% alpha alumina composition ensures maximum hardness
- Low silica content (≤0.2wt%) prevents equipment contamination
- Excellent thermal stability for high-temperature applications
- Superior wear resistance and long service life
- Ideal for steam applications and ammonia processing systems
