The balls common failure modes of grinding balls observed in different semiautogenous grinding sag applications are misshapen surface spalling shelling capping and half balls5 this paper discusses the main quality control criteria that the producers of grinding media and mines can use to minimise incidences of premature failure
Failure mode analysis looks at two types of insert failures primary and secondary primary is the initial or underlying problem for example buildup edge being unaware of the primary failure mode will result in a secondary failure mode such as chipping which would constitute a catastrophic failure
