Mining is extremely important economically and socially for the industry, especially iron ore, but along with its benefits, it also has environmental impacts generated in different ways, such as dust. This inconvenience has caused disruptions to mining enterprises, such as production shutdowns and heavy fines, as well as problems for people who work in the companies and surrounding communities, due to health problems associated with inhaling dust and dirt from the environments, making them unhealthy and devalued. Dust control mechanisms have been widely studied and one of these is dust control using spraying of suppressant solutions. Studying the efficiency of spray nozzles has become of great importance and bench tests act as efficient means of understanding the mechanism of dust abatement from minerals. Research has been common to use wind tunnels. Thus, a tunnel was built capable of evaluating 5 different nozzles and their efficiencies in suppressing pellet feed and sinter feed at two speeds and different water pressures. It was concluded that the tunnel is capable, through the methodology used, of evaluating and comparing the best nozzle, demonstrating that it is an important tool in consolidating this knowledge in the Fluid Dynamics and Particulates Laboratory.
