In the absence of a correlation between the mechanical properties of ceramic grinding media and its wear behaviour, bench scale grinding tests can be used to evaluate the wear of media. This paper illustrates the need for variability testing of the bench scale test. It furthermore elaborates on different methods to calculate and display wear results: cumulative mass loss, cumulative energy input, energy related wear rate, and wear per wear event results for different media types/sources. The sensitivity of the wear per wear event to assumed moduli of elasticity is also investigated. © 2014.
