Forged Grinding Steel Balls for Mining and Mineral Milling | 20–130mm, HRC55+ and Grade Selection
Forged or rolled grinding steel balls are described with 20–130mm size and HRC55+ hardness. The actual option is Other grit with Steel material; the body lists B2, B3, B4 and B6 grade alternatives.
Confirm selected ball diameter, material grade and manufacturing route. The abrasive-grain field also contains 45#, 60Mn and 65Mn material labels rather than a particle-size distribution. The source does not map hardness or chemistry to every size and grade.
For a mining or cement mill, provide operating and inspection requirements. No impact, breakage, wear-rate or service-life test is supplied. Request batch chemistry, hardness profile and dimensional records; high-hardness wording and ISO labels alone do not establish validated milling performance under the proposed operating conditions.
