MATHEMATICAL MODEL TO DESCRIBE THE PARTICLE SIZE DISTRIBUTION PHASE DISPERSA LATERITE SUSPENSIONS

Abstract

In this paper have been explored several laterite aqueous suspensions, which are processed in the “Pedro Soto Alba” Company, of Moa, in order to verify whether their particle size distribution can be described according to the Gaudin – Schumann and the Rosin-Rammler-Sperling models, which
are suggested in the literature for this purpose, as soon as the empirical mathematical model with normalized variables, proposed by the authors. For this study were analyzed ten industrial lateritic suspensions, with the help of the computational program STATISTIC. Their particle size distributions were measured using a size analyzer HORIBA LA-910. The results of the study showed that both models, taken from literature, partially describe the suspension
particle size distributions, in dependence on particle size ranges present in each sample. It has also been shown that the empirical model of normalized variables provides good adjustments, with high values of the regression coefficients, describing the size distributions for all particle diameter ranges present in each suspension.
