2011-2-1 The effect of mill media material properties on grinding efficiency, media wear, and power consumption was defined. High density media with optimum sizing improved milling efficiency by approximately 30%. Mill media with a low coefficient of friction resulted in reduced energy consumption of up to 2.3 times in the laboratory trials. Large size high density mill media is suitable for coarse feed grinding in IsaMills. Mill media
