Of course, gypsum is not naturally available in a usable, pelletized form for soil amendments. Gypsum rock must be excavated from mines or quarries, then crushed and ground into a fine powder. Once gypsum is in a powdered form, it is ready to begin the pelletization process. Click the image below to view our infographic on gypsum soil …

The roller mill is a short-time calcining system. Both natural gypsum and mixtures of natural and synthetic raw materials can be ground, dried, calcined and classified in this kind of mill. Bundling several process steps results in highly efficient gypsum processing. Natural gypsum and up to 45% moist FGD gypsum can be fed into a roller mill.

Gypsum is a widely used industrial material and building material. Gypsum (CaSO 4 ·2H 2 O) can be calcined and grinded to obtain β-type hemihydrate gypsum (2CaSO 4 ·H 2 O), that is, building gypsum, also known as cooked gypsum or plaster. The model gypsum can be obtained when the calcination temperature is 190 °C, and its fineness and ...
