To understand the friction and wear of working mediums in iron ore ball mills, experiments were conducted using the ball cratering method under dry and wet milling conditions, which mimic the operating conditions in ball mills. The liner sample is made of Mn16 steel, the ball had a diameter of 25 mm and was made of GCr15 steel, and the iron ore powder was screened from the magnetite particles with mesh number of 20. The results indicate that a different wear condition makes the COF change in a converse way and causes a different wear pattern in wear craters, followed by the corresponding temperature rise.
