Gypsum board, drywall or plasterboard is a building product used in modern construction for efficient, cost effective fire protection that can be easily installed and decorated. The process to produce gypsum board generally consists of calcining and or grinding gypsum powder, forming a gypsum panel product and drying off excess water.

Calcination of Gypsum. Gypsum or Calcium sulfate dihydrate (CaSo 4.2H 2 O) is a mineral of calcium that is mined in various parts of the world. It is also formed as a by-product of flue gas desulphurization in some coal-fired electric power plants. There are different kinds of Gypsum and are listed below.

A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In this process gypsum is crushed, dried, ground, and calcined. Not all of the operations shown in Figure 11.16-1 are performed at all gypsum plants. Some plants produce only wallboard, and many plants do not produce soil ...

Gypsum Calcination. Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water.

We stand as one of the leading manufacturers of Gypsum Calcination Plant manufactured from superior quality of raw materials. Some of the attributes of these machines are durability, robust, efficiency and cost effectiveness. These are fired with Petcoke, Oil, Gas and Coal Gas.

Calcination in a rotary kiln is a direct, long-time calcining process. During the process, the phases of the CaSO 4 x H 2 O system can be optimally adjusted. Rotary kilns are used for the calcining natural gypsum. In this process, pre-crushed natural gypsum is calcined in parallel flow with the flue gas.

crystal water, grain distribution and stucco plaster water content, product quality is always one of Claudius Peters' primary concerns. Optimized and automated process control, based on knowledge gained over decades of operation in calcination and grinding technology, are key considerations in the design of every Claudius Peters plant.

Calcination is the key process of the production, and the most difficult process. The conversion of dihydrate gypsum to hemihydrate gypsum is performed on gypsum powder in this process.
