Abstract
Analysis of the results of experimental studies of bulk materials mixing process in a developed laboratory centrifuge having an adapter with alternating radial channels, nozzles and blades showed that the operating parameter of the device (rotation speed) has a significant effect on the pattern of distribution of the number of particles of each bulk component (in case of formation of rarefied component flows) along the height of the vertical trap. Particularly, with increase of the rotor speed by 1.67 times the maximum mass fraction of all particles of the descending rarefied flow shifts by one cell of the vertical trap. It was observed that for two types of mixtures (with 0.67 and 0.62 ratios of true densities of the substances of the key and transporting components) the conditions of their quality mixing are met. The obtained results may be useful for verification of stochastic models of formation of rarefied flows of particles of components being mixed using a rotating adapter with radial channels, nozzles and blades.
