Summary
The abrasive wear resistance of a large group of cast steel and white iron grinding mill liners was studied using a combination of service and laboratory testing. The hardness of the liners was the metallurgical variable which correlated best with the weight losses experienced during both service exposure and pin abrasion tests. Chemical and microstructural variations were much less significant in their effect upon the relative wear within the groups of either steel or iron liners, although such variations were important in the basis for the markedly lower laboratory wear rate of the white iron liners as a group. A strong correlation was found between the weight losses measured in laboratory tests and in service, and thus it appears possible to predict the service performance of new liner materials in the subject application based upon prior laboratory testing.
