The ground gypsum exits the mill in a gas stream and is collected in a product cyclone. Ore is sometimes dried in the 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 landplaster, which may be used as a soil conditioner. In most plants, landplaster is fed to kettle

Flue Gas Desulphurisation Gypsum, or FGD Gypsum can be used as an alternative to natural gypsum. In coal-fired power stations, their by-products give rise to these gypsums. 5. What are the 2 Ways of Calcification of Gypsum? There are 2 ways gypsum is calcined to produce different types of gypsum: Beta plaster is produced when calcifications happen at atmospheric pressure. It gives Type I and
