Main System of The Whole Production Line
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.

PLC Control System And Lab Equipment
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.
