11.16 Gypsum Manufacturing - US EPA

A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In this process gypsum is crushed, dried, ground, and calcined. Not all of the operations shown in Figure 11.16-1 are performed at all gypsum plants. Some plants produce only wallboard, and many plants do not produce soil conditioner. Gypsum ore, from quarries and ...

Factsheet on: What is Gypsum?

When Gypsum ( CaSO 4,2H 2O) is ground to a powder and heated at 150° to 165° C, three- quarters of its combined water is removed producing hemi-hydrate plaster ( CaSO 4,1/2H 2O), commonly known as the ‘Plaster of Paris’. When this powder is mixed with water the resulting paste sets hard as the water recombines to produce Gypsum again. This process can be repeated almost indefinitely ...

How Gypsum is Made - AWCI

gypsum into a fine powder, called “land plaster.” The land plaster is then fed into Gold Bond’s patented Calcidyne System, where it is “cal- cined,” or heated to remove three-quarters of the water which is chemi-cally combined in the gypsum itself. The result is stucco, a very dry powder that, when mixed with water, will quickly rehydrate and “set up,” or harden. The stucco is ...

The hardness of gypsum derived from the as-prepared nano-anhydrite or conventional alabas-ter was compared for increasing water to powder ratios (Figure 6). At high water content (type I gypsum), the nanostructured gypsum was about twice as hard as the reference material. At low water content (hard stone gypsum, type IV), a very

15/01/2012  Gypsum production process. Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. Asneeded, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) in diameter. If the moisture content of the mined ore is greater than about 0.5 weight percent, the ore must be dried in a rotary dryer or a heated roller mill. Ore dried in a rotary ...
