Gypsum rock is converted into gypsum plaster by driving off some of the chemically combined water. Heating gypsum at 120C for one hour results in a hemi-hydrate (CaSO 4.12H 2O) with three quarters of the water removed. Gypsum hemi-hydrate is also known as Plaster of Paris. Prolonged heating over several hours results in the formation of

Gypsum is the name given to a mineral categorized as calcium sulfate mineral, and its chemical formula is calcium sulfate dihydrate, CaSO 4 2H 2 O. However, a broader definition includes all the calcium sulfates, including calcium sulfate hemihydrate, CaSO 4 0.5H 2 O, which is known as plaster or plaster of Paris (POP). Figure 6 summarizes the polymorphism of calcium sulfate
The MPS gypsum calcining mill can process different starting materials, from 100% natural gypsum to 100% FGD gypsum, here one machine is sufficient for grinding, drying, classifying and calcining ideal for plasterboard production. Mills of this type are currently in operation with throughput rates of 10 to 100 t/h.
gypsum calcining mill is about 2-4 minutes. This is short in comparison to the time it takes in the 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 areas first commercial gypsum operation began in 1841 when Daniel Ball and Warren Granger built a mill on Plaster Creek and turned out 40 tons of product (gypsum) in a single week. Eight years later, Richard Butterworth opened a quarry on the west side of the river, and the establishment of two more quarries extending into the hillsides near the river quickly followed.
Mill temperature is limited by supplying the mill with cool clinker, by cooling the recirculating air and, in some cases, by using an internal water spray. This must do no more than cool evaporatively, of course, and the flow of water is controlled by monitoring the loss on ignition of the cement as it leaves the mill. ... Starting with gypsum ...
