Features of Steel Grinding Media Mill Ball with Well Abrasive Resistance Top Quality For Cement and Mineral
Processing:
1) High hardness: Steel Grinding Media Mill Ball has high hardness: surface hardness can reach to 55-67 HRC, volume hardness 56-64 HRC
2) High Impact toughness: impact toughness is more than 15 J / cm2.
3) Low Broken rate: peel fragmentation resistance property of over 20000 times. The actual breakage rate is less than 1% and close to 0.
