Descripción
Raw granular materials used in cement manufacturing are limestone grains displaying a broad size distribution, ranging from microns to a couple of inches. They are stored as pyramidal heaps and, although empirical homogenization techniques are used with good results, there are important factors like segregation and grinding conditions that produce mixtures with different poorly controlled size. For this reason, the stability of the heaps strongly depends on these factors and it is important to study the influence of the respective amounts of particles of different sizes on the properties of the mixture. In this work, we report experiments analyzing the relationship between the characteristic angles of equilibrium of the heaps and the geometry, size and chemical composition of the grains. We also look for correlations between the values of the characteristic angles and the relative amounts of grains of different sizes that make up the materials. We demonstrate that the chemical composition is correlated with the geometry of the grains and that their aspect ratio does not influence the critical angles. We also show that the critical angles mostly depend on the relative amount of fine grains in the granular mixture and on the dispersion of the sizes. The results obtained allow one to draw conclusions that may be relevant to the treatment and storage of raw materials in the cement industry.
