Production process

The 1st step: Feeding&convey

The forklift put the raw material into the hopper ,and then from the hopper to the belt conveyor ,then from this belt conveyor to here, also here another belt conveyor .this conveyor is sued to put the raw material into next step.

The 2nd step: Pre-Drying

From the belt conveyor come into the hammer dryer ,(later i will show you the pictures)as you see for the chemical gypsum ,the two point is very important ,the surface water and the crystal water .so in the hammer dryer is used to take the surface water out , in the hammer dryer the temperature is very high around 400-500 degree ,and why have this step ? some factory don't have this step ,this step can make the gypsum liquidity. And then to the next step to the boiling furnace ,it can easy to calcinate ,so we have this step .
 

The 3rd step: Bad dust collector
The bag dust collector, the main function is recycle gypsum powder to reduce cost.

The 4th step: Calcination

 

The powder come into the boiling furnace (calcination ) to remove crystal water and remaining surface water.

 

For our boiling furnace, the special is , all the parts inside ,we divide to 4 chamber. The first chamber we will provide very high temperature ,and this very high temperature is used to dry the left surface water and crystal water.
The second ,third ,fourth chamber use lower temperature to provide heat to remove there main crystal water. We use this method to keep the quality of the gypsum. So both part are very important and the gypsum quality depend on this two parts :Hammer dryer and boiling furnace. This part is called the calcining system.

 

 

About the heat source: the coal-fired boiler or the natural gas burner provides heat. A part of the heat is supplied to the hammer dryer to remove the surface water, and part of the heat enters the boiling furnace to remove the remaining surface water and crystal water. At the same time, the remaining heat of the boiling furnace is recovered to the hammer Dryer . (the temperature of cooked powder is controlled at 80-100 degrees).So the heat usage is very high , more energy save ,other factory can not reach this temperature .

The 5th step: Ball mill

This part is ball mill, because the chemical powder has quality problem, through modification mill, it can change the characteristic of chemical gypsum powder, make it similar to natural gypsum.

 

The 6th step: Storage

 

After milling, the gypsum powder will come into the silo by elevator. For this part, if you want to produce plaster of Paris, there will be some connection parts to plaster plant.
 

Our advantages of chemical gypsum production line:

Features of this hot air boiling furnace technology

1-Reduce investment

2-Reduce maintenance cost

3-Gypsum powder quality adjustable

4-The installation period is short and area is small

5-energy and power saving

Our chief engineer Mr. Xie is very famous in the gypsum field in China, and his technology is recognized in the gypsum powder industry, especially in the chemical gypsum field.

Mr. Xie preside over lots of projects,especially large capacity.Only his technology could support project of capacity 400000
tons/year.
Here is a little story about why our factory protect his technology as a secret.A lot of people in the industry are trying to steal his technology.Even few people tried to steal technology from our installation site.Of cause they failed.

The technology is widely proved among the industry because of good quality,easy to operate,low maintenance rate,low energy consumption,and long service life.The most important is lots project owners reported the finished gypsum powder quality is very nice.Many gypsum board plant designate the powder produced by his equipment and technology.


The introduction of Rotary kiln:

The biggest advantage of rotary kiln technology is that the produced plaster of paris powder has a long setting time. The disadvantage is that it is not easy to seal.

Our company increase the gypsum cooling system after calcined in this production line, solve the problem of high temperature of the gypsum powder cause the Raymond mill bearing lubricating oil melt and the bad bearing, which is conducive to Raymond Mill for a long time running, Raymond machine structure is simple, low maintenance costs, the operation and maintenance personnel requirements are not high.

The high-temperature flue gas section firstly heats the gypsum powder at intervals to prevent the gypsum powder from generating too much anhydrous gypsum powder in the high-temperature flue gas. This process is indirect heating.

 

The cooled high-temperature flue gas is directly heated with gypsum powder to make full use of heat energy , the temperature of the exhaust gas is low.  This process is direct heating.

This solution reduces the excessive anhydrous gypsum produced by the disadvantage of direct calcination.

 The S-type inside the rotary kiln increases the heat transfer area, and it also helps the gypsum powder calcination uniformity better.

 

Case project abroad

 

Case 1: 

1-Project name:Natural gypsum powder&board project
2-Project capacity:
    Gypsum powder line:150000ton
    Gypsum board line : 10Million sqm/year   
3-Project technology:hot air  technology

 For this project, our Chief engineer has only taken 5 days to run the whole gypsum powder production line and put it into production after installation, and our customer also felt surprised on it. While some manufacturers need more than one month to finish it or even some are unable to run it for production. 

Case 2: Chemical  gypsum powder&POP  project This is our chemical gypsum powder project in South Africa. The customer is a well-known local building material supplier. The owner has been in the phosphogypsum industry for more than 40 years. project capacity:     Gypsum powder line: 50000 tons/year     Plaster of Paris line: 30000ton /year

Case 3: project name:Chemical gypsum powder&POP project project capacity:400,000 tons/year-500,000ton /year 3-project technology:hot air boiling furnace technology This project is one of our domestic projects with a large capacity of 400,000 tons. The raw material is chemical gypsum powder, and use the production process of hot air boiling furnace. This customer's factory is only 1 hour away from our company, and now he is currently building a second production line and its annual production capacity can be 500,000 tons. Actually we have succeeded more than 40 similar projects in our country.

Case 4: Project name: Gypsum powder&board project Project capacity: 4 factory ,8 lines totally In 2008 year: gypsum powder line 50000 tons/year + gypsum board line 8000000 m^2/year In 2009 year: gypsum powder line 150000 tons/year + gypsum board line 10000000 m^2/year In 2012 year: gypsum powder line 150000 tons/year + gypsum board line 10000000 m^2/year In 2018 year: gypsum powder line 300000 tons/year + gypsum board line 20000000 m^2/year Since 2008, the boss purchased 4 gypsum powder projects from us, with capacities ranging from 50,000 tons/year (2008) to 300,000 tons/year (2018). He has now grown to become the largest producer of gypsum building materials in Indonesia, and the quality of his gypsum powder can compete directly with the local Knauf factory and even sell at a higher price.

 It's not easy to visit the project in China now. But we have different project in different countries for visiting.
