MAXIMUM DRY DENSITY FOR A CONTINUOUS GRAIN SIZE DISTRIBUTION

A theoretical expression for the optimum packing density of a continuous particle size distribution has been derived. The constituent particles are assumed to be nondeformable spheres, devoid of bonding or cohesive properties. The calculation extended the results of optimum packing for binary, ternary, quartenary, and quinary systems to higher orders and applied them to a continuous linear grain size distribution. It is found that the theoretical upper limit in packing density, n, is dependent of mean size, but well described by a piecewise linear function in the inverse of the packing density as a function of the slope s of the distribution.
