This production line is developed by cooperating with Shanghai Caoyang Construction Adhesive Factory, whi ch had been put into use. specializi ng in Thermal Insulation material pr oduction;
This equipment has advantages of l ow investment, high output (about 5~8 T/H), low broken rate (≤0.5%), Non-Segregation and good perform ance of on-site mixing.
Fluidization System and Dosing System with Double Flap Valve
Device of Dosing Pipe Fluidization System
In the discharge and dispend material fluidiza tion system, efficient fluidization is achieved by using compressed air in small quantities, evenly distributed, through specially designed fluid elem ents in the conical section of the silo. This desig n improves the fluidity of the material, creates th e pipe lines transport of the material, makes the system compact, easy to installation, good press urize and no material remains pollution.
The main tasks of the fluidization system are to:
1 、 Lower the friction between the sil o wall and the powder.
2 、 Lower the friction between the particles in the powder, in the specific region where the material flow is desir ed.
3 、 Keep the fluidization process un der control.
Fluidization Principle 
This design is to lead the air into the silo via fluidization plates which are divided i nto modules. Each module air supply is controlled by an orifice (a fixed tiny hole) t hat will restrict the air consumption below a certain level also if there is no power preventing the air flow. The even power discharge will enable us to dose the fluidi zed power almost in the same way as a liquid, using a valve.

Of course the powder will never behave exactly like a liquid and therefore we hav e developed a special double flap valve to give a better outlet geometry during fin e dosing.

Small build-in valve is operated for accurate fine feeding
Double valves are opened for the coarse feeding
The using of double flap valve and the fluidization system makes the dosing system has high dosing accuracy, reliable function and easy to operate.

The fluidization system combined with the double flap as dosing device gives several the benefits :
High accuracy combined with high dosing s peed. Reliable and easy to clean. Low maintenance need. Fast and easy change of dosing device. Few spare parts needed. Non abrasive handling of raw materials. Compact layout of the production process.
