Abstract: The present work was undertaken in order to improve the feeding of the test dust dispersion into a cyclone separator. In order to solve the problem of deposition of the test dust in inlet pipes, a comprehensive investigation was carried out taking the powder mixing into account. With regard to the powder transportation, the effects of pertinent variables such as flow velocity, mass loading and amount of dispersant were closely examined. This work showed that the tapped density may be a decisive property to estimate the quality of dispersion, of the admixed powder with dispersant. It was also found that the effective flow velocity to transport powder must be 2-3 times greater than the semi-theoretical and empirical estimations available in the open literature.
