Mercury emission characteristics and mechanism in the
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.

Example for calculating the dust return correction
Note that: The value of (F×FA) is equal to the summation of all fuel types used for clinker production, for example (F×FA) = (F×FA) kiln fuel type 1 + (F×FA) kiln fuel type 2 + (F×FA) calciner fuel. Thus, the amount of kiln feed should be weighed during a kiln test period (e.g. 24 h), in which the operation conditions are representative for the kiln …
