Use of Gypsum. 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 whiteness are higher than that of ...
Grinding gypsum rock The crushed gypsum is fed to the ball mill for grinding until 90% of the gypsum is less than 149μm (100 mesh). The ground gypsum powder leaves the mill as a gas stream and is collected in a cyclone separator. Calcining gypsum powder
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 ...

The effects of grinding temperature on the grindability and quality of cement were discussed mainly from the standpoint of the action of gypsum. A mixture of normal portland cement clinker and natural gypsum (SO 3 =1.7% in the resulting cement) was ground in the test mill at 25-200°C, for 20-100 min. which is provided with a heating device.
Answer: I assume you mean Plaster of Paris or casting gypsum when you refer to gypsum powder. Actually, gypsum (CaSO4*2H2O) is a misnomer for Plaster of Paris. The mineral in Plaster of Paris is actually anhydrite (CaSO4). To make Plaster of Paris you …

Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4). This is calcium sulfate with a ...
Despite gypsum's widespread use and the regular need to grind it, studies concerning the grinding of gypsum ore remain scarce. In response, in this study, we have systematically investigated how certain grinding parameters (i.e., mill speed, ball filling ratio, ball size distribution, powder filling ratio, grinding aid ratio, and grinding time ...
