Function：
With continuous pre-expanders, the raw material feeding into the
pre-expansion tank as well as the foaming process run
“continuously”
They are especially suitable for high material throughputs with
almost the same densities all the way in a range of
****0g/l.
1. Chamber is made by quality stainless steels, fully engineered
structure, stable performance, high throughputs at low energy
consumption.
2. 1st and 2nd passes are both workable.
3. Simple construction and thus low maintenance
requirements.
4. Electric control, and valve system for adjustments of steam
pressure, even density is achieved.
5. Simple and reliable operation.
6. Safety protection.
7. Drying system including fluidized bed drier is optional.
