Modern Gypsum Plaster Board Production Line
The gypsum board production line is the professional equipment for producing the new paper-faced plaster
The principle work procedures includes:
1 Calcined gypsum powder, water and other additives enter into the mixer by automatic metering and conveying system. Gypsum slurry, generated from mixer after mixing, would be evenly scattered on the surface of continuous moving bottom paper.
2 With continuous moving and vibrating, gypsum slurry will gradually diffuse and evenly scattered on the surface of moving bottom paper. Then it goes into the forming machine and compound with top paper. By the process of extruding and forming, the slurry would sealed by top paper and bottom paper and bottom paper. Thus, pulpous plasterboard is formed.
3 While it conveyed by setting belt, wet gypsum board gradually formed after board shaping, natural coagulation and automatic casting. The wet boards, arranged by programmed control system, quickly enter into the dryer, through rollers, belt conveyor and board turnover.
4 Under strict controls in temperature zones of dryer, the wet board dried by different temperature hot air blow. Modified starch would stick with the paper. The dry gypsum boards would be transported out of dryer.
5 Then the board would be turned over again and folded together ( face inside), cut into certain finished product size and edge sealed.
6 Finally, it comes to automatic stacker for stacking. Then can be transported to warehouse by forklift after stacking.

5. Introduction to the equipment:
Gypsum powder furnishing system:
This system adopt the calibrated feeder, making the gypsum powder supplying is quite accurate, So it provides a great convenience for the mixing operation of the gypsum powder
Paper supplying system
This system have a unique way to pick up the paper,add the high precision rectify deviation machine which have a great help for the trimming of the board later
Water supplying system
The accurate measurement of screw pump to water supplying , which provides great convenience for operation
Foaming system:
This system chose barostat to supply the air, using screw pump which can making the foam into the slurry equably. So that we can adjust the weight of the board easily
Forming system:
This system is is developed by our technical department, chose the plate type forming machine instead of the pressing roller before. So enhance the antiwear ability of the machine,Prolong the service life of the machine, improve the the quality of the products and the flatness of the board surface
Drying system:
Hot oil
Hot oil type is using the oil temperature from the thermal oil furnace to drying the board
Dust collection system:
We chose the electronic pulse bag filter which have a good efficiency of dust collection.
Control system:
Using the PLC and sensor pieces such as variable frequency solid state relay to grantee the equipment in a good and long automatic running
Why Choose Us ?
1. Good reputation factory
2. The quality of the finished products are good
3. Low rejection rate
4. High degree of automatic
5. Low energy consumption
6. Less maintain cost
7.Our engineer will come to your country to install and guide the equipment until the quality gypsum board come out.
