2020-6-9  The significantly larger site-specific EF in the quarry 5 (8.15 g/s for two stages crushing) compared to site-specific EF in the quarry 7 (1.36 g/s for four stages crushing) is in contradiction with the EFs of US EPA and previous observations that the increase in number of crushing stages increases the amount of dust produced during the crushing [e.g. 5, 26]. Also, Bruno calculations support these
