Mined gypsum contains both quartz and dolomite [CaMg(CO₃)₂]. FGD gypsum usually possesses a much smaller and more uniform particle size (more than 95% < 150 microns) than agricultural mined gypsum that is granulated to produce a final size of 2–4 mm. However, FGD gypsum can also be processed to form larger-sized granules.

Cold crushing strength: The cold crushing strength is the resistance of the refractory to crushing, which mostly happens during transport. It only has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. Other indicators used are bulk density and porosity.

The water/gypsum ratio: Gypsum upon hydration reacts with a definite amount of water to reform CaSO 4.2H 2 O. If the water/gypsum ratio is high, then the amount of water leaving the mixture by evaporation will be high. Thus, there will be more voids left behind leading to …

After crushing, the gypsum is hauled 25 miles by narrow­gauge rail to the processing plant at Plaster City (Tucker, 1926:271- 2751 Sampson and Tucker, 1942:135,136; Ver Planck,1951:119, 121; Ver Plank, 1952:29-35, 121t, 122t; Ver Plank, 1957:233, 235, 238, Morton, 1977:52). 8 After crushing and screening the gypsum is fractioned to three circuits.

Natural gypsum, shown in Fig. 25.1, is the most common raw material for production of binders.It is a soft mineral, attributed to sedimentary rocks, normally grey or with no colour, with a humidity of about 8–10%. Gypseous stone, a denser modification of gypsum that is composed of gypsum and sandy and clayey stone, is normally used to produce gypsum binders.

crusher. The crusher breaks up those rocks larger than two inches in di-ameter; smaller rocks are fed directly into the rock dryer. The rock dryer is a huge rotating kiln or oven which evaporates any surface moisture on the rock. The dry gypsum is now ready to be ground. The rock is ground in a roller-type crushing mill called a Raymond mill.
