Then through the secondary gypsum crushing, such as impact crusher, cone crusher,etc. the mineral is crushed to less than 2cm. The end products will be transported to calcining kiln through bucket elevator. We can chanage the temperature of the calcining kiln to produce β-type hemihydrate gypsum, anhydrite and over gypsum.
Challenging quarry conditions require specialist screen washing processes to make the most of extracted construction materials. ... Gypsum is generally found underground near deposits of Limestone or other minerals formed by evaporation. ... Manufactured silt from the crushing process also needs to be removed.
Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris.

When described in broad terms the cement manufacturing process is relatively straightforward. In addition to the processes outlined, other processes include mining (quarrying), primary and secondary crushing and transport of raw materials, pre-blending, storage, loading and discharge of powder and clinker, and bagging of cement.

The addition of CaO can broaden the temperature range for calcining FGD gypsum into β-HH. In addition, with the increase of CaO addition, the quality of the converted β-HH is better. The high-performance building gypsum can be prepared by calcining the FGD gypsum with 3–5 wt% of CaO addition at 160–220 °C for 1.5–2 h.

A different philosophy applies to the crushing and grinding of Gypsum. Gypsum as a mineral (CaSO4·2H2O) is number 2 on the Mohs scale of hardness; only Talc is softer. This would lead one to believe that it should be easy, to crush, like coal for example, and our equipment was formerly designed on this basis.
