Introduction of gypsum drying and calcining process

In the production of gypsum products, the calcination process is the key link to control the quality of the product. The one-step and two-step processes launched by Dongda Powder, the Sder calciner, the Sder dryer, and the internal and external thermal boiling furnace are suitable for different heat sources. Process methods and equipment suitable for different product forms have formed a complete industrialized system. When choosing a calcination system, the use of the product, local heat source, power conditions, degree of automation, production scale, etc. should be considered, and the calcination method and supporting system should be determined.

One-step calcination process system

Automatic control, small temperature change range, stable product quality.

It is directly used in the production of wet materials, integrating drying, calcining and dispersing, with low operating cost and reasonable product gradation.

The drying and calcining time can be adjusted, which is beneficial to the adjustment of the setting time.

It is suitable for continuous production on a large scale. The heat source can be in various ways. It can be directly or indirectly heated and calcined, or the industrial flue gas exhaust of the power plant can be used as the heat source.

One-step calcination process system

The Side calciner, researched and designed by Dongda Powder Company, is a high-efficiency equipment that integrates drying, calcining and dispersing. It is also called a one-step process equipment. The gypsum is calcined by direct heating with the post-combustion gas.

Technological process: The gypsum to be calcined is fed into the calciner by the feeder. Under the action of mechanical dispersing force and hot air generated by gas, the material undergoes a process of dispersion, drying, calcination, and high-speed homogenization.
