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 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.
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.
Our advantages of chemical gypsum production line:
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.
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 introduction of Rotary kiln:

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.

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 m2/year In 2009 year: gypsum powder line 150000 tons/year + gypsum board line 10000000 m2/year In 2012 year: gypsum powder line 150000 tons/year + gypsum board line 10000000 m2/year In 2018 year: gypsum powder line 300000 tons/year + gypsum board line 20000000 m2/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. |
