The design principle of a new. friability testing apparatus for abrasive grains is proposed. The apparatus is composed of a drop hammer which gives impulsive load of a few tenth of one millisecond to the single abrasive grain (specimen), and of a piezoelectric measuring system for dynamic fracturing load at which the grain is broken down under impulsive load. Using the apparatus, the friability of some grains such as of diamond and aluminium oxide are measured quantitatively through the dynamic fracturing load. As the results, it is shown that, although the dynamic fracturing load of each grain among a group of specimens scatters widely, the averaged value on the whole increases proportionally to the mean diameter of grains tested and is considerably higher than the static one which is measured under static compressive load.The some effects of thermal shock on dynamic fracture of abrasive grains are also described in the paper.
