This production line contains a series of machine such as dust collector, ebullience calciner, Heat-conducting oil boiler etc.If you want to know more detailed information ,please consult me freely.
2. The main composition of gypsum is dehydrate gypsum©vCaSO4.2H2O©w. However, the gypsum powder used in practical production (such as the gypsum powder for gypsum board, for mould, for plastering) is to dry and dewater the dehydrate gypsum, reduce the content of crystallization water in it, so the standard of crystallization of gypsum powder can meet the needs of all kinds of gypsum powder, because it can change into plaster of pairs. Plaster of pairs can re-integrate with water when it is applied into production, and it can be processed into new type building materials with a high intensity, such as gypsum board, gypsum block, etc.
3. Existing gypsum powder drying technologies the following: the heat, produced by the burning of medium in the stove, is transmitted to frying cauldron and pipe of circumgyrate stove, then gypsum powders are added, after mixture and drying through milling equipments, the finished product is transmitted to the store house. In this way, the quality of gypsum powder is cheesy, because the content of crystallization water is uneven.
It is mainly applied to produce air-entrance brick. Autoclave, sulfur still: it is mainly applied to sulphidization and rubberizing in chemical industry and rubber industry; vacuum high-temperature sterilization, vacuum package and food sterilization in food service industry. The Autoclave can also be applied to straw steaming, sterilization and dehydration, dehydration and preservation of vegetables and plant food, vacuum high-temperature sterilization in other industries. The Autoclave can also be adopted for yarn steaming in textile industry.
Gypsum board, which belongs to green products, has a wide range of uses, and broad prospect for development. Its raw materials are taken from the nature. There's no pollution and hazardous waste during the production process. Light weight, high strength, fire resistance, heat and moisture resistance, no distortion, no crack, no contract, easy to assembly and use, all the above characters make it an irreplaceable building material.

New-type gypsum frying boiler- ebullience calciner
First grind and second bake. The largest advantage of this technique, compared with that of first grind and second bake, is energy consumption reduction. Large plaster stone shall be ground into powders with diameter less than 0.2mm, which increases the specific surface when calcining, enlarges the contact area with heat medium, improves calcination heat exchange efficiency and lowers energy consumption greatly. This equipment has small bulk, large production capacity, and simple structure and is hard to destroy.
Analysis on technique features:
I. Concept of technique
Crusher grinds large gypsum into small granules less than 25mm. After storage and measurement with weigh belt, transfer them into Raymond mill for milling. Transfer qualified calcined gypsum powder to clinker bin for storage or to board-manufacturing workshop for usage.
II. Technique advantages:
Features of first grind and second bake:
Compared with that of first grind and second bake, the largest advantage of this technique is great energy consumption reduction. The reason lies in: great plaster stones are ground into powders with diameter less than 0.2mm, which increases the specific surface when calcining, enlarges contact area with heat medium, improves calcining heat exchange efficiency and lowers energy consumption greatly; the disadvantages are three powder pollution positions in technical process, which shall be solved with dust-removing equipment.
Features of two other techniques:
First bake and second grind: due to high energy consumption and low production capability of this technique and that the quality of the products is hard to control and is unstable, at present, it is a kind of backward technique and is seldom adopted. Only a few small factories are still applying it.
Integration of grind and bake: this technique has good features: low energy consumption, small investment, high efficiency, stable quality of the products and small area coverage. Besides, the dust volume is concentrated and is easy for protecting environment. However, it is not mature at home and only BNBM imported from German one set of Peters-mill, which runs to manufacture thistle board.
