Gypsum - an overview ScienceDirect Topics

In Building Decorative Materials, 2011. 3 Calcined Gypsum. Calcined gypsum is produced when dihydrate gypsum is fired at the temperature of 800-1100 °C. At this time, a little calcium sulphate is decomposed to generate new phase CaO, which gives calcined gypsum certain hydrating ability. The condensation speed of calcined gypsum is slow.

Calcination Temperature of Gypsum - bulk-online

Jul 24, 2007  Hello; I am working in a gypsum plaster plant and I have been given a task that is related with comparing our current calcination system with our other subsidiaries' calcination systems. To compare them, I got a questionary about the system. One of the question was "what is the calcination set point". At the first glance, I thought that is the outlet temperature of the stucco.

Purity Determination in Gypsum Application Note Gypsum

Gypsum is a mineral found in natural rock. It is extracted either by quarry­ ing or mining. Pure gypsum contains 79.1% calcium sulfate (CaSO 4) and 20.9% chemically bound water (H 2O). However, since gypsum is a natural material, pure gypsum is rarely found. Natural gypsum typically contains up to 15 to 20% impurities such as lime, clay and ...

The pin mixer evenly distributes the binder, creating an easy to handle material, and more control when pelletized gypsum is created on a disc pelletizer. Using a pin mixer for gypsum conditioning also allows for a higher throughput, a reduction in the amount of binder required, and more high-quality, consistently sized gypsum pellets.

Features and Benefits - Rapidwall

Gypsum (calcium sulphate dihydrate) is a material that calcines at a relatively low temperature (150°C - 180°C) to produce the required hemihydrate product. The proportions and forms of dihydrate, hemihydrate and anhydrite in the plaster product are very sensitive to calcining conditions, particularly temperature.
