The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition. A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect hightemperature processing within a .

In the present embodiment, tons per hour of gypsum are supplied to the calciner cylinder in order to produce 5 tons per hour of calcined gypsum. The hot air inlet pipe 38 is one of several means by which hot air enters the calciner cylinder 26, all of which will be seen to be arranged to produce a high velocity clockwise rotary motion of hot gases and gypsum powder within the cylinder 26.

Gypsum wallboard was shown to absorb formaldehyde in a prototype house and in a measuring chamber, as reported previously by researchers at Oak Ridge National Laboratory (ORNL). Also as reported previously, formaldehyde concentrations attained equilibrium in two phases in response to a change in the air exchange rate or to the removal of the formaldehyde source.

Since calciner technology was introduced in the 1960s, there has been no comparable leap in the pyroprocessing technology for the manufacturing of cement. Steinbiss in [1] provides a good overview of earlier developments in calciner technology, as well as a prediction of the economic prospects of burning residual materials.

Gypsum (calcium sulphate dihydrate) is of great industrial importance with over 95,000 ktonnes being used in the world per annum. The greatest use of gypsum is in the production of plaster (calcium sulphate hemihydrate) for use as an interior finisher. Plaster is produced by the calcination (thermal decomposition) of gypsum.

Waste gypsum boards contain up to 10 wt% water, which needs to be removed at the rotating drum dryer. The dry gypsum is led to a ball mill to reduce the particle size to create a d 50 of 0,1 mm. The very fine material is transported to the calciner. In the calciner gypsum dihydrate is converted to gypsum hemihydrate, which is also known as stucco.

Abstract: An apparatus for calcination of gypsum includes a gypsum calciner having an interior wall surface with a circular or annular configuration as seen in its plan view, and a tubular combustor positioned at a center part of a body of the calciner. Raw gypsum is calcined or dehydrated by a high temperature gas spouting flow (Hg) ejected from a lower portion of the combustor.
