Product Highlights
Superior Wear Resistance: Features an incredibly low wear loss rate, significantly extending the service life of the grinding media and reducing long-term operational and replacement costs.
High Density & Hardness: With a Mohs hardness of 9, the high specific gravity delivers maximum impact and crushing force, dramatically improving ball mill grinding efficiency and reducing processing time.
Zero Material Contamination: Highly pure alumina composition ensures that no undesirable colors, impurities, or metallic particles are introduced into the milled materials, which is essential for high-grade ceramics, glass, and white cement.
Excellent Chemical Stability: Highly resistant to corrosion from strong acids and alkalis, allowing for both wet and dry grinding operations in harsh chemical environments without degradation.
Perfectly Spheroidized Shape: The smooth, perfectly round surface minimizes internal friction and prevents damage or excessive wear to the inner lining of the milling equipment.
