Highly efficient calcination of gypsum to hemihydrate. The calcination is controlled by a thermocouple within the stucco bed that changes the feed to maintain a constant temperature, just like a full sized industrial calciner. Calcination of the gypsum takes place in this fluidized bed. Contact Supplier. Privacy Policy 106/744, 106/787. calcination gypsum line are oftentimes used for a variety of works including but not limited to millworks, artworks, industrial works and a whole lot more. US $60000-$120000 / Set. The rate of production of gypsum plaster by a continuous calcination process, in which a mass of gypsum being calcined is maintained in a fluidized condition predominantly by the water vapour evolved during calcination, can be considerably increased and a plaster product of reduced water demand be obtained by introducing an aridizing agent such as calcium chloride along with the gypsum and controlling the temperature in the vessel at a value substantially below that previously employed, i.e. This history, when combined with other … As described in that Patent and as operated hitherto, the temperature in the vessel is controlled in the region of 150°C.

Ad. H2O) can be obtained, which is architectural gypsum, also known as plaster of paris and plaster. Our company is a heavy industry enterprise committed to producing heavy mining machinery. Calcination occurs at approximately 120 to 150°C (250 to 300°F), and 0.908 megagrams (Mg) (1 ton) of gypsum calcines to about 0.77 Mg (0.85 ton) of stucco. The calcination of gypsum, i.e. Colour may be gray, red or brown due to presence of some foreign materials like as clay, iron oxide or oxides of other materials. Due to the numerous roles, these calcination gypsum line play in a multitude of purposes, they have to be very persistent and should withstand pressure over time. It is a material with high versatility that can be applied from wall coverings to decorative ornaments. Gypsum is the mineralogical used term to describe materials that are mainly constituted of calcium sulfate dihydrate (CaSO 4 .2H 2 0). Calcination temperature can be set at approximately 135-180℃ and can be tuned to minimize residual gypsum and soluble anhydrite production and maximize hemihydrate production.
