Kilns are normally fired with pulverized coal or gas at one end. Raw materials are fed to the kiln at the back end, furthest from the burners. Travelling through the kiln, the ingredients are progressively heated. Here, flue gas flows in the opposite direction. The kiln can be divided into three zones – drying, calcining and burning.

The approach taken in this work incorporated small- and full-scale testing to accomplish several goals: 1) develop an objective method for measuring the calcination depth of gypsum wallboard, 2) assess the utility of the calcination depth surveys in full-scale fires, and 3) characterize the impact of suppression water on calcination depth Get price >>
Using the illustrated figures, height in calcining zone 5.1 m (Fig 3), height in preheating zone 0.9 m, hieght in cooling zone 2.5 m, 8.5 m corresponds to the total height of kiln. It may be concluded that the raising the calcining temperature, reducing the stone size and growing the kiln height are essential for increasing the lime production. Get price >>

calciners may be operated in either batch or continuous mode. In flash calciners, the gypsum is directly contacted with hot gases, and the stucco product is collected at the bottom of the calciner. At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. Get price >>

Calcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances. 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.
