2、 Introduction of gypsum board equipment


1. Batching section


The materials in the silo are transported by the horizontal and vertical conveying equipment, and sent to the belt scale by the rigid impeller feeder. The surplus material will be sent back to the silo through the return conveyor, hoist and other conveying equipment. Building gypsum, modified starch, accelerator, glass fiber (used in the production of water-resistant gypsum board and fire-resistant gypsum board) and other raw materials are measured respectively, and then mixed in screw mixer and continuously sent into vertical mixer. The foaming agent is added to the storage tank. When used, the foaming agent and moisture are sent to the foaming device from the metering pump, and the compressed air is generated to generate stable foam and send it into the vertical mixer. After the edge adhesive is prepared in the tank, it is sent to the glue spraying ports on both sides of the forming station, and the adhesive tape is sprayed on both sides of the paper on the gypsum board. The upper and lower face protection paper is transported to the paper holder by the electric hoist.


2. Forming section


The molding paper is sent to the molding station through the paper storage machine, tension device, scoring device and deviation correction device, and the gypsum slurry flows to the molding paper from the vertical mixer. The paper feeding machine is sent to the forming station after the paper storage machine, tensioning device, deviation correction device and glue. The forming machine is plate type with adjustable thickness. The molding machine gathers the upper paper, lower paper and gypsum slurry to extrude and wrap the board with specified thickness. The formed gypsum board belt is stably sent to the cutting machine through the solidification belt conveyor and the conveying roller table, and cut according to the set length. Then it is sent to the type 1 transverse conveyor by the acceleration roller table, and then to the dryer after closing to the roller table.


3. Drying section


The dryers are divided into two zones. The hot steam is used as the heat source. While the hot air dryers advance slowly in the dryers, the hot air dryers continuously exchange heat with the hot air flowing longitudinally. The dryers absorb heat, the temperature rises, and the free water in the dryers evaporates slowly, but it does not damage the crystal water of dihydrate gypsum. When the gypsum board comes out of the dryer, its water content should be less than 1%. After the gypsum board is dried by the dryer, it is cooled by the cooling section of the dryer, and then it is discharged from the dryer orderly by the plate discharging machine.


4. Trimming and stacking section


The gypsum paper out of the dryer is transported by roller conveyor, 2-type transverse conveyor and laminating machine, and then sent to the trimming machine for accurate cutting to the required size. The finished board is sent to the stacker for stacking by roller conveyor, and then sent to the finished product warehouse by forklift for storage.




3、 Introduction of gypsum line equipment


1. High output, simple operation, daily output of 2000-10000


2. Low cost, less personnel, 5-6 people per shift, less power consumption, total installed capacity of more than 20 kW.


3. The equipment adopts numerical control operation, simple operation, automatic production, automatic grouting, automatic net laying, automatic flattening, automatic cutting and starting to produce finished products with stable quality.




4、 Gypsum mortar plastering equipment




The equipment can produce plastering gypsum, self leveling gypsum, putty powder and other powder mixed products. Gypsum mortar equipment is automatic production line, cement, gypsum, auxiliary materials, sand and other main raw materials are in bulk, stored in raw material tank. The main raw materials are automatically proportioned by computer measurement without manual feeding, which avoids the unstable product quality and other problems caused by manual proportioning. Because the raw materials are transported in a closed environment, the phenomenon of large dust will not appear, and the production environment will be greatly improved.




1. The equipment is mainly composed of raw material storage tank, screw conveyor, metering bucket, bucket elevator, raw material mixing bin, horizontal gravity free mixer, finished product bin, automatic weighing and packaging machine, electric control box, dust collector and ladder platform support.




2. The preset formula is input into the computer, and the raw materials such as cement and sand are transported to the batching scale through the screw conveyor according to the proportion. After weighing, they are lifted to the mixing bin by the bucket elevator and put into the horizontal gravity free mixer for 3-5 minutes (slightly different according to the mixing time of different materials). After that, it falls to the finished product warehouse, and the lower part of the finished product warehouse is equipped with all automatic weighing and packaging machines to bag the mixed finished products. In the packaging process, the above batching, mixing and other processes can be repeated to achieve assembly line operation and provide production efficiency.




3. The production line is a two-layer platform mode, and the raw materials to be mixed warehouse is designed, that is, the raw materials are stirred and mixed. At the same time, the next batch of raw materials are lifted to the mixing bin to wait for mixing, which saves the lifting time of raw materials and greatly improves the production efficiency




This equipment requires the factory to be 8.5-9.0 meters high, and can be produced by 3 or more people. The utility model has the advantages of small land occupation and large output.




The equipment is equipped with automatic weighing valve mouth packing machine, which can pack one bag every 4-6 seconds, greatly improving the production efficiency and reducing the production cost.
