Effects of particle size and size distribution on estimating erosion wear of cast iron in sand-water slurries

Erosion wear of cast iron has been evaluated in a pot tester for narrow-sized and multi-sized particulate sand-water slurries. The effects of particle size and size distribution on erosion wear have been analyzed and the applicability of median diameter or weighted mean diameter as an effective particle size for multi-sized slurry for estimating erosion wear has been investigated. It is observed that the mean particle size of the narrow-sized particulate slurry can be taken as the effective particle size for evaluating the erosion wear. However, the observed trend of variation of erosion wear with particle size is not followed by median or weighted mean diameters of multi-sized slurries, showing large deviations.
