  • Ball Mills an overview | ScienceDirect Topics

    8322 Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter ( Figure 811) The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weightTherefore, the mechanical properties of the steel ball should be: 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 toThe use performance and mechanical properties of ball
