The effect of media size and properties on milling efficiency, media wear, and power consumption will be discussed. A predictive model has been developed and was verified by analyzing results of laboratory trials in a mineral grinding application. Recent developments in high density media capabilities for a range of feed types and particle sizes will be presented.
Research Highlights► 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 cost is not the only factor to be considered in selecting the best media for a specific application.
