ADVANTAGE ANALYSIS:

This product has advantages of: High specific gravity, excellent toughness and impact Resistance, low wear loss, smooth surface, fine chemical stability, good erosion resistance and non-contamination to grinded material. If appropriate charging ratio can be made, it can reach high grinding efficiency with fineness researching D50≤2μm. It is the most ideal grinding media for ultra-fine grinding.
