Forming section

 

The upper and lower paper is conveyed to the cardboard station by electric hoist. The lower paper goes through 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 powered materials and liquid materials, flow out onto the lower paper at forming station. Meanwhile, the upper paper goes through tension device, swing correction device, and edge adhesive and then to the forming station. The upper and lower paper together packs the plaster slurry to get plasterboard with specified thickness. After going through the setting belt conveyor, the formed plasterboard has certain strength.

 

The wet plasterboard with certain strength are conveyed to the cutting machine stably via 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 board 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 materails dosing, example water, foaming agent, other additives

3. model: 3

4. the photo listed below shows advanced technology

 

 

 Dry material dosing 

The building plaster is conveyed to the weighing belt 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 pre-mixed in a special powder mixer for making additives homogeneously distribution and then conveyed into the slurry mixer. 

 

Wet material 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 the slurry mixer directly.

The adhesive glue prepared in the tank is applied on both side of the upper paper of the plasterboard with the level difference.

Note 1: it is better that buyer choose local workers for doing installation & erection with our engineers together. so that local workers can learn it quickly.

1. local workers and our men will find a name for all the parts. so that buyer can buy it quickly in future. or just mark an item with technical data & area

2. our men will tell local workers which parts easy to be damaged, which parts danger, which parts should be filled with lubricating oil, how to change, where is spare parts

3. the normal problems, how to change paper roll, the skill on mixer, dryer, programme etc.

4. with time passing, the local workers will be skilled men, and all of them will be a big family

5. any problem, or misunderstanding, please tell us directly. normally we always face problem, finally all of us can solve it together. example food, working time, habit, language etc.

 

 

 

 

 

Paper supplying section

1. 4 pcs paper holder. stable performance, easy to change, very cheap

2. load paper roll by crane quickly

3. need forklift

4. germany type is TOO expensive, and maintenance charge is also TOO high. their machine structure is very complicated, buyer has to wait for professional workers to solve it once problem there

5. the technical data of paper

Moisture content                                     %                 7~10

water absorptiveness                             g/m              215~20

Air permeability                                                           80~120

(s/100ml/in)

 

 

 

 

 

 

 

Note 2: installation of dryer

1.  name: dryer

2. function: dry gypsum board

3. price: about 60% of total price, the most important part

4. which technology in the photo listed below: natural gas directly burning, also called new type hot air technology. it is popular in europe

5. you also can see setting belt, and control room in the photo listed below

 

 

 

 

 

 

 

Note 3: performance testing after installation

1. two steps here, one for performance testing of single machine, one for performance testing of one section and whole production line

2. normally waste some gypsum boards, but they can be used again 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
