Emission Estimation Technique Manual
2005-9-13 · The ground gypsum exits the mill in a gas stream and is collected in a product cyclone. Ore is sometimes dried in a roller mill by heating the gas stream, so that drying and grinding are accomplished simultaneously and no rotary dryer is needed. The finely ground gypsum ore is known as kettle feed, which may be used as a soil conditioner.
The ground gypsum leaves the mill and is conveyed to a dust collector. Calcining. Plaster or stucco is made by calcining the raw gypsum to convert the dihydrate into a hemihydrate, and is known as calcined gypsum. In some plants, landplaster is fed to kettle or flash calciners to produce plaster. Calcining occurs at about 250°-300°.
