emission factors for dry grinding

11.24 Metallic Minerals Processing

Emission factors for PM-10 from high-moisture primary crushing operations and materialhandling and transfer operations were based on test results usually in the 30 to 40 weight percentrange. However, high values were obtained for high-moisture ore at both the primary crushing and thematerial handling and transfer operations, and these were included in the average values in the table.A similarly wide range occurred in the low-moisture drying

Emission Factors for Abrasive Materials

Abrasive blasting materials, such as coal slag garnet and copper slag, are often used for cleaning metal surfaces to remove rust and to prepare a surface before the application of a coating. The pre-blast and post-blast (spent) abrasive materials contain traces of heavy metal constituents such as Cr, Mn, Ni, Pb Fe, and Ba. Hence, the health risk associated with the resultant particulate emissions is a source of
