The cement clinker manufacturing process can be divided into mill-on and mill-off modes according to the raw mill operating conditions (Li et al., 2019, Zheng et al., 2012). When the raw mill is running during the mill-on mode, the flue gas from the precalciner passes through the raw mill into the dust collector before being emitted.
