Carbonate gypsum ore is gray, dark gray, granular, brecciated. its main mineral is gypsum, containing dolomite, calcite and anhydrite. anhydrite ore is dense and hard with the color of white, gray or light blue. the main minerals are anhydrite, gypsum the sum of the two is greater than 85, a small amount of montmorillonite, hydromica.
Grinding, for example in a ball, rod, or hammer mill, is necessary if the gypsum is to be used for high quality plasterwork or for moulding, medical, or industrial applications. Unlike with other cements, such as lime and Ordinary Portland Cement, special mills for mineral grinding may not be required and the relatively soft gypsum could be ...

A larger fraction of SO 3 is added to cement in the form of calcium sulfate, either as gypsum, CaSO 4 2H 2 O, or anhydrite, CaSO 4. During cement grinding, a fraction of the gypsum may be decomposed to hemihydrate CaSO 4 ½H 2 O. The main role of calcium sulfate is to control cement setting, although strength may also be affected.
Gypsum is often found in considerable thicknesses within evaporite sequences and in association with limestones and shales. Large deposits of alabaster gypsum are commonly observed at the sole of many large-scale tectonic dislocations and thrust faults. ... The main production procedures are breaking, heating and grinding.
The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%. Role of Gypsum in Cement The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water.
We would like to show you a description here but the site won't allow us.
Why gypsum is added in cement? Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of cement".

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.
Introduction. Gypsum is monoclinic mineral, and its main chemical component is calcium sulfate (CaSO4). Natural dihydrate gypsum (CaSO4·2H2O) is also known as raw gypsum, after calcination, grinding can be obtained Beta-type hemihydrate gypsum (CaSO4·1/2H2O), that is, building gypsum, also known as plaster, plaster.
Gypsum is a soft sulfate mineral composed of calcium sulfate dehydrate, with the chemical formula CaSO₄ 2H₂O.
