The authors discuss in the present paper about the compaction energy of“the powdery layers”, when the statically compressive load is appllied to the powdery layers in a steel mortal, and then carry on investigations on the relationship between the compaction energy and the tensile splitting strength of the cylindrically combined“powdery layers”.In this paper, the authors will advance a proposal that the compaction energy is equal to the area under a connecting link between the intersections of hysteresis curves as shown in Fig. 1.The tensile splitting strength of“the powdery layers”is directly proportional to the compaction energy per unit volume. The proportional constant is to be decided by the characteristic values of grindability CEI. The authors have derived Eq. (19) as the basic relation between the tensile splitting strength and the loading condition.
