Understanding the Effects of Liner Wear on Semi-autogenous

Understanding the Effects of Liner Wear on Semi-autogenous Grinding Mill Performance. Abstract The effect of liner wear on SAG mill performance has gained much attention in recent years. It is commonly observed that the three key performance criteria of SAG milling throughput power and product size all improve as the liner wears.
