Category： Gypsum Powder Calcination Equipment
Description: Yifeng Machinery Co., Ltd is specialized in the design and manufactured various types of machinery etc, especially is good at gypsum application machinery!
Gypsum stone or industrial by-product gypsum is present in the form of two water calcium sulfate. There are two crystalline water in its formula. Only when 1.5 crystalline waters is produced, the hemihydrate calcium sulfate will be gelled. The process of removing crystalline water is gypsum calcination.
The inner continuous burnt gypsum calcination kiln completes the calcination and dehydration by the direct contact of high temperature flue gas with raw gypsum materials. As the material complete heat exchange with the flue air directly in the device, the thermal efficiency and heat utilization of equipment is much higher and calcinated quickly and energy consumption is quite low. It is 40-50kg/t generally. The scale is large, single equipment can reach 100-200 thousand tons; the environment is good, high degree of automation and the product quality is stable. However the product performance is relatively single, application scope is narrow, and it is generally suitable for scale production of gypsum.
