EPS Batch pre-expander(double expansion)

Main Features

1. The machine adopts PLC and touch screen, automatic filling, temperature control,material level control to realize automatic production.

2. Machine is complete with Screw Conveyor.

3. The closed constant pressure foaming barrel has high heating efficiency and saves steam.

4. High precise guiding pressure reducing valve controls the temperature and steam pressure of the closed barrel, ensure the outcome pressure of the valve constant and the inner temperature controlled within ±1%, which keeps the foamed material equal and prevents the bead agglomerate because of the bad temperature control.

5. With photocell or vibration sensor to control material level, ensuring density tolerance within ±3%.

6. The machine is equipped with fluidized bed dryer, including drying,automatic sieving, delumping and material conveying to silos.

7. Most components are of world-famous brands, with reliable performance, stable quality, long service life and low maintenance cost.

8. The machine can realize the primary and second expansion.
