Second stage: gypsum is crushed into particles smaller than 30mm, and transported to grinding mill. Third stage: separator delivers fineness-qualified raw gypsum powder into the furnace firing, the rest comes back to the grinding mill again. Fluidized bed furnace is the most widely used equipment for calcining building gypsum.

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.

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°.
