SUMMARY The objectives of our project are to establish an industrial estimation method for any powder bed yield loci and to develop a design procedure for an industrial powder process by use of the yield loci. In this report, research works on the phenomena of powder, in which fluidization, packing structure, adhesion and agglomeration, mechanical yield etc. are contained, are systematically reviewed. Examples of the application of the method for estimating powder bed yield loci to actual particulate processes are discussed. Finally, the transmission of particle bulk density in powder is described qualitatively and experimentally.
