Description：
The environment in primary ball milling can best be described by giving equal considerations to both impact and abrasive conditions. The relatively large ball sizes employed [3″ – 4″ (75 – 100 mm)] contribute a significant impact component to the overall wear. 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 and lower drop heights resulting from the use of smaller balls and smaller mill diameters, respectively.
The feed ore in primary grinding mills is typically very abrasive owing to its particle size, shape, and mineralogy. Wear speeds approaching or exceeding 20 µm/hr. have been measured for very abrasive Au. Cu, and Mo ores, while wear speeds on the order of 10-15 µm/hr. have been encountered in softer primary ores.
Steel grinding media used in primary grinding must be designed for maximum abrasive wear resistance while maintaining good toughness. Toughness is particularly important in grate discharge mills where pulp levels at the discharge end of the mill can approach zero.
