Product Description
1.Main process
1.1Paper supply system
It adopts special pneumatic shaft and magnetic powder brake. The high accuracy paper connecting way and high precision electro-hydraulic alignment device,along with the automatic marking device played very big roles for shaping,and ensured the good appearance quality.
1.2.Gypsum powder supply system
It takes the exclusive impeller feeder and high precision weighing belt as the core of powder feeding. Thus it ensured normal supply of the gypsum powder.Moreover,it contains series of powder additive storages,discharging and metering feeding system;glass fiber cutting and its metering feeding system .etc.
1.3.Water supply and mixing system
It has the accurate screw measurement pump and visual liquid flow meter device which lead great convenience for operation which lead great convenience for operation.
1.4.Foaming system
It adopts high volume pressostat for gas supply,got screw metring pump and advanced dynamic and static combined foaming system which makes the foam uniformly enter into the mixer. Thus it has a key effect on improving product quality and testing products' weight.
1.5.Forming system
The vertical mixer and the pneumatic forming device are made of special werable stainless steels which enhance the systems wearable ablity and prolonged its span.The vertical mixer got pin type,none-pin type and other types to choose.
1.6.Conveying system
This system adds the waste board dumping device which reduces the intensity of labor and ensures the cleaness of workshop.
1.7.Drying system
The drying system is the core of the whole production line and it affects the quality and the energy consumption of the products. It has interior muti-layer coiler heat releasing type, external finned heat exchanging type,and hot air direct drying type. According to the airflow direction,it has longitudinal airflow type,transverse airflow type,and longitudinal,transverse combined airflow type.And it also can configure waste heat recovery system under customer's demand. Inside of the dryer,there are various regulation and controlling mechanisms to stabilify the temperature and airflow of each layer freely,thus it guarantees the quality of the gypsum board,and reduces energy consumption.
1.8.Heating system
Most of this system use the organic thermal carrier boiler(thermal oil boiler and hot air boiler),which takes coal,oil,and nature gas as main fuels.The thermal oil type boiler takes thermal oil as the carrier and the the oil is carried into the heat exchanger of the dryer by the high presure oil pump,as for the hot air boiler,it makes direct use of the hot air and blow it to the dryer,fully make use of the energy, and reduces the cost.
1.9.Edge cutting and sealing system
After turning over and folding the board,the system cuts the folded board and seals it together. The waste raw material cutted is chopped into powder to absorb slurry,then it can be used accelerator. The sealing system adopts advanced technology from abroad and domestic which reduces cost and improves efficency.
1.10.Dust removal system
This system uses the pulse blow bag dust collector which improves the dust removal effect and makes it reach the environmental standard. In addition,it is convenient to deal with the dust and recycle.This system is good for the country and the people.
1.11.Control system
All of the three control stations adopts PLC control system,AC contactor and drive device chose reliable brand, and it also uses the contact-less equipment such as frequency converter,photo-electric sensor etc whicj Insure the reliable operation and realize the long-term and continuous fully automatic running of the gypsum board production line.
2. Finished gypsum board Specification
Dimension of gypsum board:
Thickness: 7mm-22mm
Width: 1200mm or 1220mm
Length: 1800mm~3600mm
3. Types of Gypsum Board
a) Common paper surface gypsum board
b) Fireproof paper surface gypsum board (H)
c) Waterproof paper surface gypsum board (S)
4. Advantages of Gypsum Board
1) Product quality: product quality is priority to the international standard GB/T9775-1999 (equal to European Standard).
2) The gypsum board which produced by the gypsum board production line is heat-resistant, fire-resistant, insulated, light, nonpoisonous, little pollution, adjusting the humidity of the room.
5. specification of production line
it based on the output of 2 million sqm gypsum board production line.
