Natural gypsum powder production line typically involves several stages, from mining and extraction of gypsum rock to the processing and production of gypsum powder. Here is a general overview of the process:

1. Mining and Quarrying:

The process begins with the extraction of natural gypsum deposits from mines or quarries. Gypsum is a mineral composed of calcium sulfate dihydrate.

2. Crushing and Screening:

The extracted gypsum rock is usually crushed into smaller pieces to facilitate further processing. Crushing equipment, such as jaw crushers and cone crushers, may be used for this purpose.

3. Grinding:

The crushed gypsum is then finely ground into a powder in a grinding mill. This step is crucial for producing the desired particle size and surface area of the gypsum powder.

4. Calcination:

The ground gypsum powder is subjected to calcination, a process where it is heated to a high temperature to remove excess water and convert the calcium sulfate dihydrate into calcium sulfate hemihydrate (commonly known as stucco or plaster of Paris). The calcination process typically takes place in a rotary kiln.

5. Drying:

The calcined gypsum, now in the form of stucco, is further dried to eliminate any remaining moisture. This step is crucial to ensure the stability of the gypsum powder.

6. Milling and Classifying:

The dried stucco is milled to produce the final gypsum powder. During this process, the powder is also classified to control the particle size distribution.

7. Packaging:

The final step involves packaging the gypsum powder into bags or other containers for distribution and use. The packaging may be done manually or through automated systems.

Note:

It's important to note that the specific details of a natural gypsum powder production line can vary depending on factors such as the quality of the gypsum deposit, the desired properties of the final product, and the scale of production. Additionally, modern production lines may incorporate advanced technologies to enhance efficiency and sustainability.

Environmental considerations are also crucial in gypsum production. For instance, efforts are often made to minimize environmental impact through responsible mining practices, efficient energy use, and proper waste management.
