Abstract

The porosity and bulk density of granular materials are closely related to the issues connected with the transport and storage of this type of materials. The article discusses the basic factors determining porosity and bulk density. Additionally, the influence of the two of these factors (moisture, shape factor) on the obtained values of bulk density and porosity was investigated. Non-linear estimation was performed in order to obtain an influence model of the analyzed factors. With respect to bulk density, the model was well fitted to the input data; yet, for porosity, the goodness-of-fit failed to be satisfactory.
