May 15, 2022Thus, atmospheric mercury emissions during the mill-off mode accounted for 35.0%− 71.7% of the emissions during the entire cycle, although the mill-off period only lasted for 5%− 17% of the whole cycle. Our results therefore suggest that supervisory monitoring of mercury in cement clinker production should specify the operating status of raw mills.
