With continuous pre-expander, the raw material feeding into the pre-expansion tank as well as the foaming process runs “continuously” They are especially suitable for high material throughput with almost the same densities all the way in a range of 12-30g/l.
1.Chamber is made by quality stainless steels, fully engineered structure, stable performance, high throughput 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.
