properties of steel balls for ball mill

The use performance and mechanical properties of ball mill

Therefore, 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 to

Ball Mill an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
