Main system
First Step-Raw Material Conveying And Drying System
Forklift put the raw material into the hopper, and then from the hopper to hammer dyer by the belt conveyor.
Second Step-Drying System
To dry the surface water of the powder with temperature around 500-700 degree,it can increase the liquidity of the gypsum powder and make it easy to calcine after come into the boiling furnace. it's our core technology.
Third Step Cacinating System
The function of the boiling furnace is to remove crystal water and residual surface water. In this part ,we equipped waste heat utilization device, with this device , the waste heat can be reused in the hammer dryer to dry the surface water ,So the discharge heat temperatuer is low than 100, so it is more enegry saving .
Four Step-Milling 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,it can increase the specific surface area of the powder.
Then Packing Machine And Silo
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.
Technology Advantage
1. Continuous output: using hammer dryer and soft start.
2. Stable quality: The modified mill can increase the specific surface area of the material.
3. Energy saving and stability: adopt the latest hot air boiling furnace technology, heat recycling, and more energy saving.
4. High-performance equipment: use cloth bag dust removal, water bath desulfurization, and denitrification treatment, and Greet brand inverter. Siemens Electric, PLC, Guomao reducer, GB cable, electrical control: ABB.
5. Simple control: It adopts computer display and PLC control.
6. Mature experience: The core feature of our company is the mature technology for sale, which can lay a solid foundation for your company.
7. The maximum technical capacity can reach 1000 tons/day.
8. Reasonable layout and low maintenance rate.
9. Short installation and debugging time.
Installation
Method one
Our engineers are going to our customer's site to install.
Method two
Our engineers can guide the installation online.
Project case
Project Name:Natural Gypsum Powder&board Project
Project Capacity:Gypsum Powder Line:150000 tons
Gypsum Board Line : 10Million sqm/year
Project Technology:Hot Air Technology
Project Current Situation:Running Well
Project Location:Middle Asia
Our Uzbekistan project was in Bukhara, which is owned by a Chinese man and an Uzbekistan man together.
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 about it. While some manufacturers need more than one month to finish it or even some are unable to run it for production.
Why we can let our customer let finished powder in 5 days after installation?
Firstly, our calcining technology is different and more advanced than other manufactures.
Secondly, it benefits from our experienced engineers who has investigated and tested many projects, especially in gypsum powder projects.
In addition, it's not just the simple assembling of each part for the gypsum powder project, but its important reasonable and professional design for the whole production line.
Packing
Whole after sales service
Pre-Sales: Full Cooperation With Pre-Preparation Work
In addition to the technical aspects of the project itself, our support also includes assisting clients in obtaining feasibility reports, government approvals, bank approvals, etc.
In-Sales: On-Time Reporting of Production Progress
You could inspect the production of your machine through photos and videos for the whole procedure.
After-Sales: Lifetime & 24h Technical Support
We offer a lifetime of technical support. Feel free to contact us for help with any technical issues,24 h available. We will also visit customers regularly to help them solve problems and assist to update formulas and equipment.
