Finished machine:
1, name: forming machines
2, models: 5 models with different technology and prices
3, model in th photo lists below : FM-03 (Standard quality), popular in China market for capacity 5 million m²/year
4, normal packing method: plastic package
Forming section:
The upper and lower paper is conveyed to the cardboard station by electic hoist.The lower paper goes through the cardboard tension device,indentation device and swing correction device to the forming station,while the plaster slurry of certain consistency ,which is formed in the vertical mixer from various kinds of solid powder materials and liquid materials,flow out on the lower paper at forming station.Meanwhile,the upper paper goes through tension ,swing correction device,and edge sealing adhesive and then to the forming station. The upper and lower paper together packs the plaster slurry to get plaster board with specified thickness. After going through the seting belt conveyor,the formed plasterboard has certain strength.
The wet plasterboard with certain strength are conveyed to the cutting machine stably vis roller conveyor and cut as per preset length (little longer than the finished product),then conveyed to 1# transverse conveyor via accelerating roller. In which, the rejected is conveyed out of the production line via reject board belt conveyor and the qualified board is turned over and queuing to enter the dryer.
Dosing system
1, dry raw materials dosing, example gypsum powder, modified starch, other additives
2, wet raw materials dosing, example water ,foaming agent, other additives
3, model: 3
4, the photo listed below shows advanced technology
Dry materials dosing
The building plaster is conveyed to the weighing beld via bucket elevator ,screw conveyor and rigid vane feeder and then conveyed into the screw conveyor for mixer. This system has material internal circulating function for over flow of material sent to weighing belt to make conveying process quite stable.
Modified starch and other dry additives are conveyed to the screw conveyor for mixer after metering.
Glass fiber used for producing water resistant and fire resistant plasterboard is added to the screw conveyor for mixer after cutting.
The above mentioned dry materials premixed in a special powder mixer for making additives homogeneously distribution and then conveyed into the slurry mixer.
Water materials dosing
This production line has special foaming device.After metering,the foaming agent and water is pumped to the foam generator respectively via screw pump, the compressed air is also conducted into the foam generator after metering. The foam generator produces stable foam and sends it to the vertical mixer directly.
Water is pumped into slurry mixer directly.
The adhesive glue prepared in the tank is applied on both sides of the upper paper of the plasterboard with the level of difference.

Note 1: It's better that the buyer employs the local workers for installation & erection with our engineers together and the local workers can learn quickly in that case.
1, local workers and our men would find a name or just mark an item with technical data & area for all the parts which can help the buyer purchase them quickly in the future.
2, our men will let the buyer know which parts easy to be damaged ,which part is dangerous,which part should be filled with lubricating oil,how to change ,where to purchase spare parts .
3, the ordinary problem,such as how to change paper roll, the skill on mixer, dryer,programme etc.
4,with time passing, the local workers will become skilled men with sufficient experience
5,if there is any problem or misundrstanding ,please feel free to let us know . Pepple tend to face problems at first place but we will work together to solve it.for example, food,language,working time,manners and customs etc.
Paper supplying section
1, 4 pics paper holder, stable performance ,easy to change ,reasonable price
2, load paper roll by crane quickly
3, forklift is needed
4,Germany type is way too expensive and maintenance charge is also too high.The structure of machines is rather complicated and buyer has to wait for professionals to solve it once the problem comes out.
5,The technical data of paper :
Moisture content % 7-10
Water absorptiveness g/m 215- 20 of 60 seconds
Longitudinal tensile strength N 230
Transverse tensile strength N 60-70
Air permeability 80-120 ( s/100ml/in )
Note 2: intallation of dryer
1, name : dryer
2, function: drying gypsum board
3, aboput 60% of the total cost,the most vital part
4, technology in the photo listed below: natural gas direct burning also named new-type hot air technology which is popular in Europe.
5,you also can see setting belt and control room in the photo below
Note 3 : performance testing after installation
1, two steps here,one for performance testing of one section and whole production line.
2, normally waste some gypsum board,but they can be used as raw materials
3, adjust machine programme by local workers,with the help of our skilled engineers
4, normally we do this slowly,so that more local workers can know more
After Sales Service
1. We promise to reply in less than 24 hours
2. We will try to control the delivery in the shortest time than you expected and required.
3.Our engineer will come to your country to install and guide the equipment until the quality gypsum board come out.
