Gypsum rotary kiln
Rotary kiln for gypsum
Fuel: coal, heavy oil or natural gas
Application: gypsum board, gypsum block, plaster of Paris, etc.
Gypsum rotary kiln is a type of rotary kiln that is commonly used in the production of gypsum. Rotary kilns are widely used in industrial processes for heating materials at high temperatures in order to cause chemical reactions or physical changes.
Applications of Gypsum Rotary Kiln
- Gypsum rotary kilns are primarily used in the production of plaster of Paris, which is a white powder used as a building material and for decorative purposes. Plaster of Paris is made by heating gypsum to around 150°C, which causes it to lose water and become calcium sulfate hemihydrate. The hemihydrate is then ground into a fine powder, which can be mixed with water to form a paste that hardens into a solid when it dries.
- Gypsum rotary kilns are also used in the production of other gypsum products, such as gypsum board, which is commonly used in the construction industry. Gypsum board is made by mixing gypsum with additives and water to form a slurry, which is then poured onto a sheet of paper and sandwiched between two layers of paper to form a panel. The panel is then dried and cut into the desired size and shape.
- Gypsum rotary kilns are also used in the production of gypsum blocks, which are similar to concrete blocks but made with gypsum instead of cement. Gypsum blocks are lightweight, fire-resistant, and have good acoustic insulation properties, making them ideal for use in interior walls and ceilings.
About raw materials
The primary raw material used in the production of gypsum is calcium sulfate dihydrate (CaSO4.2H2O), which is also known as gypsum rock. This material is obtained from mines and quarries and is crushed into small pieces. The crushed gypsum is then ground into a fine powder, which is used in the production of various gypsum products.
Other raw materials used in the production of gypsum include water, fuel, and additives. Water is used to hydrate the gypsum powder, which is necessary for the formation of calcium sulfate hemihydrate (CaSO4.1/2H2O), the primary component of plaster of Paris. Fuel is used to heat the kiln and maintain the high temperatures necessary for the chemical reactions that take place in the kiln. Additives are used to modify the properties of the gypsum, such as setting time, strength, and durability.

Highlights of gypsum rotary kiln
- Efficient gypsum calcination: Gypsum rotary kilns are a highly efficient method for calcining gypsum. Through the rotation of the drum and high-temperature operation, the rotary kiln ensures complete calcination of the gypsum block, resulting in higher yields and greater purity.
- Suitable for various gypsum feedstocks: Gypsum rotary kilns can accommodate a variety of gypsum feedstocks, including natural gypsum, synthetic gypsum, and recycled gypsum. This flexibility allows producers to adjust their production processes to changing market demands and availability of raw materials.
- Versatile product applications: Gypsum rotary kilns produce a range of high-quality gypsum products, including plaster, wallboard, and gypsum blocks, which have diverse applications in the construction, agriculture, medicine, and art industries.
- Energy efficient design: Modern gypsum rotary kilns are designed with energy efficiency in mind, using features such as high-efficiency burners and waste heat recovery systems. This reduces energy costs and environmental impact while maintaining high levels of productivity and product quality.
- Customizable to specific production needs: As a versatile and flexible production tool, gypsum rotary kilns can be customized to meet specific production needs and goals. Manufacturers can tailor the kiln’s design, control system, and other features to optimize performance and ensure maximum efficiency and profitability.
Working Principle of Gypsum Rotary Kiln
The working principle of gypsum rotary kiln is similar to that of other rotary kilns. The kiln is a long, cylindrical vessel that is inclined slightly from the horizontal and rotates slowly about its axis. The gypsum raw materials are fed into the kiln from the upper end and move slowly towards the lower end as the kiln rotates. The fuel is burned in the lower end of the kiln, producing heat that is transferred to the gypsum materials.
The high temperatures inside the kiln cause a series of chemical reactions to take place. The first reaction is the dehydration of the gypsum, which occurs at a temperature of around 150°C. During this reaction, water is removed from the gypsum, resulting in the formation of calcium sulfate hemihydrate.
The hemihydrate then undergoes a second reaction, called rehydration, at a temperature of around 170°C. During this reaction, water is added back to the hemihydrate, resulting in the formation of gypsum. This final product is then cooled and collected at the lower end of the kiln.
