This study presents the relationship between the particle size distribution of powders and the density of the randomly packed bed. Since the binary particle groups which consist of two sized particles are the most fundamental particle ones with size distributions, the random packing models of them were made by computer simulation and investigated for the packing density dependent upon the particle size ratio and the volume fraction of the large spheres.<BR>The results are summarized as follows:<BR>(1) In the bnary random packing the density increases with the piarticle size ratio, and the maximum value exsists near the volume fraction of 0.72.<BR>(2) The maximum packing density can be expressed by a simple function of the particle size ratio. From the equation 0.75 is estimated for the maximum packing density at infinity of the particle size ratio.<BR>(3) The packing density can be mathematically expressed by the function of the particle size ratio and the volume fraction.
