3.5.2.2 Ball Mills. The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.

To verify the accuracy of the DEM model, validation are carried out by simulation and experiment of Banisi and Hadizadeh (2007) within an industrial semi-autogenous grinding (SAG) mill used in the Sarcheshmeh copper ore dressing plant in Iran, and the inner size of which is 9.60 × 4.88 m. Inside the SAG mill, there are 60 steel rail-type liners, and each liner contains a lifter with a ...

SAG mills are currently the technology of choice in hard rock milling operations for reducingSome mechanical design issues to consider for feed endliners are: • ensure good fit of FE parts with the conical mill head (and mount parts on sound backing rubber) — poor fit can lead to bolt failure and...
