Comparative table of gypsum production schemes -

Gypsum cement is produced by fine grinding in ball mills with addition of activating additives. To increase water-resisting properties, portland cement or slag-portland cement, granulated or dump slags, boiler ashes, crushed bricks or dolomite dust are added. Adding only lime although increases water-resisting properties, but decreases cement strength greatly.

Hydration of anhydrite of gypsum (CaSO4.II) in a ball mill ...

01.04.2005  From the results, the following mechanism can be proposed for the conversion of anhydrite into gypsum during hydration in a ball mill. As soon as anhydrite comes into contact with water, a part of it is dissolved, making the solution saturated with respect to Ca 2+ and SO 4 2− ions. These ions, which are hydrated in the solution, rapidly get adsorbed at the surface of anhydrite, giving a higher

Gypsum - Wikipedia

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 42H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including Ancient Egypt,

Cement clinker - Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Five stages of gypsum production process Stone

15.01.2012  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 pulverised in agricultural mills.
