An attempt to characterise the abrasivity of a particle's geometry using a numerical descriptor, the 'spike parameter', is described in this paper. The 'spike parameter' is a measure of a particle's abrasivity and is based on representing the projected particle boundary by triangles at many scales. The calculation of the parameter involves measuring the perpendicular height and sharpness (apex angle)...
In the work presented a new technique of characterising particle abrasivity based on the representation of the particle boundary by triangles at different scales has been developed. Initially, a number of artificial particle boundaries were constructed and analysed showing good correlation with their ‘intuitive’ abrasiveness. Later the abrasivity of four types of typical mineral abrasives was characterised...
