  • Cast Grinding Steel Balls - 911Metallurgist

    The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in SAG mills. The increased frequency is due to the Increase in charge volume (35 – 40% versus 5 – 10%), higher mill speeds, and the larger number of balls per unit charge weight. The lower impact forces are due to a combination of both smaller ball masses

  • hardness of balls in ball mill grinding

    First, ball mill ball has higher hardness and higher HV/E value, in order to resist the grinding of hard abrasive grain. Second, ball mill ball has enough toughness (KI) to resist impact and crack propagation. Third, ball mill steel ball has good anti fatigue ability, in order to resist the effect of alternating stress and impact fatigue wear.
