• The meaning of study on single particle crushing is recognized at which it is regarded the accumulation of single particle crushing as the comminution performed in practical operations stochastic phenomena. Especially, experimental data concerning the mechanical properties of brittle solids measured under dynamic loading are so far very few. Further, the experimental data concerning compressive strength, sphere compressive strength, fracture energy, new surface produced and fracture surface energy in single particle crushing under dynamic loading are next to nothing. From these situation in this field, thus experimental results arranged in order are reported in this paper. Besides, the parameters on single particle crushing are considered to be necessary to clarify on the following themes in the future. These are the effect of environmental conditions on single particle crushing, the conversion of fracture energy in single particle crushing and the correlation between ordinary grinding and single particle crushing. In this study, the entire experimental data were obtained under the loading state by keeping the mechanical force balance between internal force and external corresponding to the specimen and loading machine. When the experiment is carried out under impact loading with a shock, a little different data are expected to be obtained. With respect to this issue, as it is in the midst of the investigation, the results will be presented in the near future. The new surface produced of fractured product having a wide range of size distribution was estimated by assuming the shape factor is to be 6.0 in this paper. These experimental values do not give the real new surface produced in its strict meaning. Therefore, the measurement of surface area of irregular particles having a wide range of size distribution is also necessary to be investigated in the future.
