Dust spread of bulk cargo loading is a potential environmental hazard, which can negatively affect human health and pollute environment. It is one of the most common ecological issues in city harbors and industrial areas, which are located close to residential areas and where large amount of granular materials is transferred. A significant amount of granular cargo is lost as dust, causing negative impact on the environment and the loading process costs. Dust spread is also a significant problem in agriculture, where granular materials are loaded for transportation or desiccation. In order to minimize the dust formation and eliminate dust spreading different types of dust suppression systems are used. In this paper several geometrical configurations of dust hopper constructions are modelled and analyzed. CFD and discrete element method software packages are used for analysis of granular particle flow through the dust control hopper system under different system parameters. Several types of granular materials are used for analysis of the hopper system. Granular material flow is analyzed with different hopper shape and granular material distribution loading parameters. Particle distribution at the hopper nozzle outlet is also analyzed under different vibration frequencies.
