Gypsum powder is one of the five major gel materials, which is processed through crushing, grinding and other processes. It is widely used in construction, building materials, industrial molds and art models, chemical industry and agriculture, food processing, medicine and beauty and other applications. It is an important industrial raw material.
Gypsum has good sound insulation, heat insulation, and fire resistance properties. It is abundant in natural gypsum reserves in China and has been used for a long time. With the improvement of economic and technological levels, gypsum powder production equipment and production processes have also gained more choices and more scientific configuration schemes.
Equipment configuration for gypsum powder production line
The production process of gypsum powder can be basically divided into three stages: crushing, grinding, and calcination
Crushing stage
The size specifications of the extracted gypsum ore vary, and suitable crushing equipment is selected according to the actual situation for preliminary crushing treatment, resulting in particles with a particle size of no more than 35mm.
1. Jaw crusher
The feed particle size of the jaw crusher is ≤ 1200mm, the discharge particle size is 10-350mm, and the production capacity can reach 1-1000t/h. Suitable for rough crushing and processing large blocks of gypsum, with strong crushing ability and high crushing ratio.
2. Counterattack crusher
The feed particle size of the impact crusher is ≤ 1300mm, with a production capacity of 30-2000t/h. It is suitable for medium to fine crushing of gypsum with low hardness and Mohs hardness level 2, and the discharge particle size is very good and uniform.
3.
Mixing System,The vertical mixer is made of wear-resistant stainless steel special materials, which greatly enhances the anti-wear ability and prolongs the service life. Building gypsum, modified starch, coagulant and other raw materials are respectively measured, mixed into the spiral mixer, and continuously sent to the vertical mixer
4.,Foaming agent system,The dynamic and static combined foaming system is used to produce uniform and stable foam, which is sent into the vertical mixer to effectively reduce the weight of the paper gypsum board and enhance its thermal insulation and thermal insulation performance
5,Board Type Forming System,we use a new type of molding machine, can produce 7-25mm thick, 1100-1300mm wide paper gypsum board, adapt to the main line speed 0-120m/min, the upper and lower molding board with fine adjustment function, can effectively control the thickness balance of gypsum board, the upgraded feed end can effectively and automatically distribute slurry, instead of the previous manual distribution, with automatic gluing process. Automatic detection and control of glue liquid, automatic detection of broken paper, to ensure the production of gypsum board thickness high standard, effectively improve the quality of gypsum board.
6,Conveying System,After the formed gypsum board belt is transported by the solidifying belt machine, it is smoothly sent to the cutting machine by the conveying roller table, cut off according to the set length, and then sent to the 1# transverse conveyor, where the waste board is sent out of the production line by the waste belt, and the qualified board is sent to the dryer by the distribution machine for drying
7,Cutting System,Using servo cutting machine, the length of the broken ruler is more accurate, which can reduce the loss of gypsum board
8,Drying System,The system belongs to the core part of the entire production line, which directly affects the quality and energy consumption of the end product. We have a variety of technologies such as thermal oil drying, hot air drying, direct drying, etc., which can help customers accurately analyze and recommend the best solution according to the local fuel situation of customers
9,Edge cutting and Sealing System,The sheet is cut to the required size by the trimming machine, then stacked by the stacker, and sent by forklift truck to the finished product warehouse for inspection and storage. After sawing, the waste is automatically pulverized and transported back to the powder system for use, making full use of the waste and reducing the production cost
10,Control System,
Controlling systems of the plant consists of pulp preparing and forming control, cut off control, wet plate delivery control, dryer control, product treatment control and computer station control and etc. For electric system, the controlling system consists 4 big: pulp and forming station, wet plate delivery control ,dry station and product treatment station. Computer station is optional, which is used to monitor production line
