Place of Origin: Shandong, China (Mainland) Brand Name: HUAMIN Model Number: Nonstandard Products Application: Mill,Cement Plant,Power Station,etc, Mine,Cement,Electric Power Plant,Chemical and other industries Material: Steel Dimensions: 20-150MM Diameter: Dia.20mm-Dia.150mm Surface Hardness: 55-67HRC Core Hardness: 45-63HRC Certification: ISO9001, ISO14001,ISO18001 Packaging: Steel Drum or Steel Barrel,Container Bag Drop Test Times: more than 2000 Impact Value: more than 15J/cm2 Raw Material: High-Quality Round steelGrinding Media  Ball   Features and Advantages: Concentrating on wear-resistant grinding material for 30 years, Huamin Brand steel grinding ball is excellent in surface quality, hardness, and resistant to impact and abrasion. It won't crack and lose circularity easily. 1) High hardness: Huamin forged grinding steel ball has high hardness: surface hardness can reach to55-67 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.       Grinding Media Ball   Technical Parameters:   Nominal Diameter(mm) Dimensional Tolerance(mm) Roundness % Φ20 ±2 ≤6 Φ25 ±2 ≤6 Φ30 ±2 ≤5  Φ35 ±2 ≤5 Φ40 ±2 ≤5 Φ50 +3,-1 ≤4 Φ60 +3,-1 ≤4 Φ70 +3,-1 ≤4 Φ75 +3,-1 ≤4 Φ80 +4,-2 ≤4 Φ90 +4,-2 ≤4 Φ100 +4,-2 ≤4 Φ120 +4,-2 ≤4 Φ125 +4,-2 ≤4 Φ130 +4,-2 ≤4 Φ140 +4,-2 ≤4  Φ150 +4,-2   ≤4     Grinding Media Ball   Chemical Composition:  C: 2.00~3.60    Si: ≤1.20    Mn: 0.50~1.50    Cr: 1.5~3.0    Mo: ≤1.00     P≤0.80  S≤1.00   Raw Material  As we know, the quality of forged grinding piece depends on the material by 80%.
