title: Influence of size and density of particles on flow properties of granules.
abstract: The patent apparatus for measurement of pouring of powders and granules, as well as enlarged version of apparatus for measurement of angle of repose were applied for examination of granules and their mixtures. Straightlinear association of flow time with diameter of particles of the fraction was revealed. The relation was described with linear equations. Changes of the angle's value of their mixtures were influenced by variation of the apparent density of granule, as well. The patent apparatus and their modification are suitable devices for investigation of the angle of repose and the flow time of granules.
