grinding mill wear patterns

Prediction of the disc wear in a model IsaMill and its

1 Introduction IsaMill is a horizontal high speed stirred mill that operates with very high power intensity It has been increasingly used in the mineral industry for fine and coarse grinding, because of its high energy efficiency compared with other conventional grinding techniques (Gao et al, 2001)Inside the shell, there are rotating grinding discs mounted on a shaft, which is coupled toThe 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 semiautogenous 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 inspectionWear and Failure Analysis of SemiAutogenous Grinding
