Gypsum dryer Introduction
With increasing environmental awareness, China's coal-fired power plant emissions of sulfur dioxide in flue gas increasingly tight control, power plant desulfurization imperative now gypsum dryer drying gypsum processing technology and equipment is not entirely the the same as natural gypsum, such as in material handling, dust treatment, calcination process and other: on the physical properties of natural gypsum and gypsum also have different place; such as high-purity gypsum; free water large; fine granularity; uniform particle size particle size distribution; grade with the poor; standard thick water consumption; water-soluble salts containing more; also worth noting that the two different sources of gypsum and natural gypsum; gypsum to unreacted calcium carbonate as the main impurities and are not fully oxidized Asia the presence of calcium sulfate; impurity state quite different; Jinyang Machinery Gypsum dryer The production process technology to deal with different, different limestone raw ingredients, the quality of different fineness of limestone, gypsum processing is different, based on customer needs, Jinyang gypsum dryer technology staff will customers a reasonable allocation of technology and processing methods .
Gypsum dryer Advantage
1) Jinyang Gypsum dryer Heat transfer area equipment, compact equipment structure, small footprint device.
2) Heat utilization is high, the steam consumption per ton of gypsum powder does not exceed 1t.
3) 1.0MPa steam as a heat source to meet the following gypsum dryer drying requirements.
4) gypsum dryer has a heat recovery system to reduce system power consumption.
5) Zhengzhou Jinyang Machinery self-developed high efficiency desulfurization gypsum and gypsum unloading the dryer, which not only fill the gap, but also reached the level of similar products at home and abroad, to ensure that the system efficient and stable operation.
6) It has no secondary air dust pollution, exhaust emissions meet the national environmental protection requirements.
Gypsum dryer technology
Gypsum Gypsum Application mainstream dryer after drying Jinyang high efficiency wet plaster after drying is to use as cement retarder; or workout forming hemihydrate gypsum, used in the manufacture of gypsum board, gypsum block, stucco plaster Architectural Plaster processing by heat transfer can be divided into two kinds of direct and indirect method:
1, indirect method (drying and calcining two step)
Drying and calcining the second step is based on the energy situation and environmental requirements of the power plant, will easily prolapse of the free water and water of crystallization is difficult prolapse split conducted in both devices, make it more reasonable, but also facilitate the adjustment of product structure and quality control. The device can produce dry gypsum (cement retarder use), super-excellent product gypsum.
2, direct method (drying and calcining step)
Drying and calcining step method is the use of a gypsum calcination process means high heat and mass transfer efficiency of the three-cylinder drying technology research development and design. The process means may produce dry gypsum (cement retarder use), also hemihydrate gypsum can be produced, production of dry gypsum air temperature only 120 can take advantage of low-temperature thermal power plant flue gas.
Utilization and development prospects of Gypsum
After drying gypsum gypsum dryer in the building materials industry it is widely used, processed through different means, basically can replace most of the natural gypsum production of building materials. Comprehensive processing and application of domestic gypsum has started , Prospect tremendous market opportunities, particularly those lacking natural gypsum and gypsum-rich resources in economically developed areas, the application proved Gypsum is a high-grade precious resource, it can be adapted to different uses of gypsum production of building materials, gypsum Jinyang gypsum dryer after dealing with a even better than natural gypsum gypsum binder by dry, dehydrated processed into plaster, plaster can be divided according to products: pouring plaster; gypsum plaster; ceramic industry with plaster; plaster casting industry; dental plaster material; orthopedic medical plaster bandages; strengthen coal mine fire lane wall with plaster; gypsum soil improvement and so on; the largest amount of plaster used in construction (construction plaster ).
