(57) Embodiments of a system and a method for manufacturing calcined gypsum can include an in-line calcination control device having an x-ray analyzer. The x-ray analyzer is adapted to analyze at least one of the calcined gypsum being discharged from the calciner and the calcined gypsum being fed into a mixer of a gypsum boardline. The x-ray analyzer is configured to determine the proportion of different calcium sulphate phases found therein which can be used to control at last one of the calciner and the boardline.
