Study Of Liner Wear In Ag Mills

The wear and failure analysis of shell liners of a grinding mill is investigated.Metallurgical and tribological studies were conducted on the worn liner of a semi-autogenous grinding mill in chadormalu industrial complex.The chemical analysis, wear mechanism, microstructural variations and mechanical properties in different sections of the worn liner were evaluated using visual inspection.
