At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills.
calcining, the conversion of the calcium carbonate (CaCO3) in the lime mud into calcium oxide (CaO) in the kiln product. Energy is required to cause this endothermic reaction to occur, but there are other energy components to the overall energy demand of the kiln as shown in Slide 16. There is the energy required to dry the mud, as well as losses of energy as heat from the kiln
