Optimal size distribution to obtain the densest packing : A different approach

Historically a number of models were proposed about the problem of the best size distribution for densest particle packing. In general, they show a weak point in the insufficient consideration of particle morphology that, on the contrary, it is a fundamental parameter to shape an optimal size distribution. In the present work a different approach with respect the traditional models is proposed. By means of a mixture design it was possible to define models able to predict the density in function of size distribution. The results shown the effect of particles morphology: mixtures rich in fine particles permit to obtain the densest packing. The mathematical models obtained, in the form of polynomial, fit well the experimental data.
