Resumo
This paper aims to investigate the usage of water for pellets bed humidification in a conveyor belt to improve the cooling processes and minimize dust emission during pellets transportation. Laboratory and field tests were carried out to understand the effect of pellets moisture on particulate matter emissions, the impact of solar irradiation on the moisture index, the interference of pellets porosity and the water penetration in the pellets bed layers. The results show that quantities about 2% of water content drastically decreases dust emissions (over 95%) if compared to emissions caused by dry pellets. The moisture index decay rapidly due the solar irradiation, the moisture is not uniformly distributed if water is applied superficially in a conveyor belt and the iron ore pellets, due to its porosity (ranging from 30% up to 42%) were able to retain moisture in their cores.
