Calcining kettles are in common use for calcining gypsum and like materials. Normally gypsum rock is ground up to form a powder and the powder is introduced into the calcining kettle and heat is applied to cause dehydration of the gypsum to the extent desired, with the moisture content leaving the kettle overhead in the form of steam.
Many systems additionally include options for grinding capacity before, during and after calcination, depending on the intended products. Commercial equipment to perform the calcination process include rotary calciners, flash calciners, kettle calciners and fluidized bed calciners to make beta plaster or autoclave calciners to make alpha plaster.

gypsum kettle which may range between 60 and 200 minutes. Due to the kettle being heated indir-ectly the specific thermal energy requirement is about 20 % higher than when the gypsum is cal-cined directly in the gypsum calcining mill ( Tab 1). The quantity of the water to be evaporated in the calcining process also plays an important role.

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 ... Emission factors based on the kettle and the hot pit do not apply to batch kettle calciners. mReferences 3,6,10. n References 3,6,9.
The intermediate product is calcined in the downstream gypsum calcining kettle. The product properties can be varied. The ground and calcined products with their medium to long setting times are mainly used as basic material in wall plaster or as molding plaster in the ceramic industry and as special plaster.

Calcining in gypsum kettles is a batch process. Ground gypsum is charged into the top of the kettle when it is at a temperature of 110° C. (230° F.). The temperature is then raised slowly until it reaches about 120° C. (250° F.), at which point the gypsum seems to boil, owing to the steam being emitted from the hydrated calcium sulfate.
