Photo 1: performance testing

First, test single machine. Second, test one section. Finally test whole production line.

If capacity is 15 million m2/year, this testing will takes about 10 days.

Note: normally seller will not supply it. The size is too big, transportation charge will be too high.

Our suggestion: seller supply drawing. buyer weld it on site. Buy can save money & time via this method.

Photo 4: second floor platform

 

This production line has special foaming device. After metering, foaming agent and water is pumped to the foam generator respectively via screw pump; compressed air is also conducted into the foam generator after metering. The dynamic foam generator produces stable foam and sends it to the mixer directly.

 

Water is pumped into the slurry mixer directly.

 

 

Adhesive glue prepared in a tank is applied on both side of the upper paper of the plasterboard.

Function: get wet gypsum board with certain thickness

 

 Description:

the upper and lower paper together converge into by extruder with slurry in between. The distance between the upper and lower plate of the extruder is adjustable according to board thickness, with thickness indicator on it.

 Photo 7: installation of dryer

 

Heat recovery technology is used with the dryer. The circulation air would be blown into special heat recovery exchanger to heat coming fresh air, to save huge amount of energy.

 

 

The plasterboards are conveyed into the10-layer dryer in order by distributor. 

The dryer is of 3 zones. Natural gas or LPG/GAS/MAZUT is used to heat the circulating air of the dryer directly. In the dryer, boards are dried in hot air and free water in the board is vaporized while combined water remains. Moisture content of finished plasterboard is controlled within 1~3%.

 

 

 

 

Photo 8: burner ---  germany brand

Burner is very important part for dryer. While dryer is most important & expensive part of whole production line. So we have to choose best quality & brand.

 

 

 

 

 

 Photo 9: dry gypsum board releasing part

There are altogether 3 waste dry board discharge roller tables or outlet, before booking, before edge cutting and before stacking, to discharge waste board after checking or store dry boards temporarily when consequent equipment is not in order.

This design can promise 100% quality gypsum board. What is more, the defective gypsum board will not be dried for saving energy. And all of those defective gypsum board can be used again as raw materials.

 

  

 

 

 

 

 Photo 10: booker & edge sticker

 

The dried plasterboards pass through roller conveyor, belt conveyor, 2# transverse conveyor and booking machine, and come to edge cutting section or edge treatment section, where boards are cut into exact size with great accuracy and dust are collected. Immediately board’s edges are wrapped in pairs with paper bands by each side, on which company logo could be printed.

 

 

 

 

 

 

 

Photo 11: control system

 

The whole control system adapts central and distributional topology, with local computer controlling different machines and upper level computer to monitor and modify all the important process data.

 

 

 

Distributed control

 

Making board production line in electrical control first layer set up engineer workstation, engineer’s station responsible for system maintenance and modification, production records (day and month), the second layer MODBUS network connection into site and equipment.

 

 

For the first layer, engineer workstation, main controller in the backbone network, the main controller using Siemens S7-300 series PLC, and communication can be easily extended. For the second layer using unshielded twisted pair, each branch station and long-distance I/O hang under the main controller. This structure of the controller, data exchange among workstations is fast, reliable, intuitive process, simple operation, easy maintenance, good expandability. The entire distribution system has the following features:

 

Configuration, PLC, touch screen control

Touch screen is a new type of programmable control terminals, the new generation of high reliability and high-tech man-machine interface, programming is simple, easy maintenance, with configuration software and PLC greatly improves the entire production line automation control.

 

 

S7series PLC are with high speed of operation, rich command, powerful communication, high reliability, easy operation, programming flexibility and good anti-interference ability. 

Configuration software, combined with touch screen PLC control frequency in the closed-loop system is a trend of automation, allowing operation in the industrial computer, touch screen set target directly through the PLC compared with the actual value of computing, directly to the inverter system to give directions, so as to control purpose inverter output frequency. And real-time monitoring system is charged with the actual value of the size and frequency converter with a number of parameters, the realization of the alarm, records and other functions.

 

 

 

 

 

 Photo 12: dust collecting system

This part is very important in develped countries for protecting environment & workers' health. But many small scale gypsum board plant does not have this for saving money.

 

 

Dust collection and plant ventilation

All the location that produce dust will be equipped connected to dust collection system both in board plant.

In all the control rooms, there should be air condition.

In plant building roof ventilation fans should be installed during architect construction.

 Photo 14: traditional gypsum production

1. make it manually

2. smaller investment

3. easy to learn

4. make full use of gypsum powder (normally buy more gypsum powder)

5. produce more gypsum production, your clients have more choices

 

 

 

 

 

The last photo: new-type gypsum plates 

1. made by machines

2. more pattern & color (DIY production)

3. cater for young people

4. very beautiful for interiror decoration

5. no competitor

6. if you buy our gypsum board production line, we can supply this machine to you with very good price
