Fugitive dust emission control study for a developed smart dry fog system
The DFDSS was installed in a crushing and screening plant of an iron ore mine in India. Performance study indicted fugitive dust emission concentration values ranged from 354 to 7040 μg m−3, which was reduced to 91–300 μg m −3 after installation of DFDSS. The reduced values were within the permissible limit of 1200 μg m −3 at a ...
