Here are two methods for calcining natural gypsum and desulfurized gypsum: low-temperature calcination and high-temperature flash firing. Both methods can produce plaster of paris (semi-hydrated gypsum), which can be used in the fields of building materials such as gypsum mortar and plastering gypsum, paper gypsum, etc. ,Putty powder. Anhydrous gypsum, used for floor gypsum, high-strength gypsum, etc.
It is suitable for direct heating dryers, indirect heating dryers, airflow rapid calcination, fluidized bed combustion boiler calcination, wok calcination and other processing technologies. There are downstream drying and countercurrent drying drying methods. We are a manufacturer specializing in the production of gypsum calcination processes. We can provide you with professional solutions and technical support based on the characteristics of local gypsum.

• The forklift delivers the gypsum raw materials into the large anti-blocking silo. There is a belt weighing scale at the bottom of the silo to control the material conveying speed.
• This process uses coal as the heat source and is equipped with a coal injection machine and a combustion chamber.
• The material enters the dryer from the belt conveyor for calcination and is flash-fired at high temperature. After calcination, the material enters the cooler. The cooled material enters the ball mill for grinding and modification. The finished product is transported to the material tank by an elevator.
• A temperature controller can be configured to reduce air loss in the induced draft system and increase drying output. Real-time monitoring and control of material temperature to improve thermal efficiency.
• We accept customization of dryers made of different materials, such as carbon steel, stainless steel, special alloys, etc.
• Provide product quality assurance and have CE IOS certification.
