Using Abrasion Index for calculating Steel Balls and mill …
Also we observe for SAG mills that ore competence and feed size distribution, being major influence on rock to steel ratio in the mill, are significant factors that influence SAG mill steel wear. We've observed the abrasion index to be a less useful means of predicting SAG mill grinding media wear.
A Hybrid Intelligent Framework for Maximising SAG Mill …
Mineral processing plants commonly employ semi-autogenous grinding (SAG) mills for size reduction within their grinding circuits. Despite autogenous grinding (AG) mills, which rely exclusively on the ore for grinding purposes, SAG mills utilise a combination of steel balls and coarse ore to achieve the desired discharge particle size [2].
SAG Mill Liner Peening
Peening is also related to the metallurgy of the liner material - a more ductile liner will peen more easily, a more brittle liner will be more likely to shatter or break. Work hardening of the liners at the end of their service life can make a ductile liner more brittle.
