EPS pre-expander / foaming machine / beads making machine
EPS pre-expander is a machine to expand eps (expanded polystyrene) raw material into big, light beads which can be used for packing or construction.
EPS pre-expander can’t work individually. The manufacturer has to prepare a steam boiler and an air compressor to work with the pre-expander together.
We Have 3 types of EPS pre-expanders：SPJ1200, SPJ1400, SPJ1500.
|Expander Chamber Diameter||1200mm||1400mm||1500mm|
|Condensate water Outlet||⌀80mm||⌀80mm||⌀80mm|
|second expansion||no second expansion function||80-90m3/hour||90-100m3/hour|
|Workshop Height Required||5m||6m||6m|
To expand eps, it required to use eps pre-expander. We can also call it eps foaming machine or eps beads making machine. Auxiliary machines such as steam boiler, steam accumulator, air compressors are also necessary because the expansion can’t work without steam or compressed air.
We can get different densities of eps beads from 4.5kg/m3 to 40kg/m3 according to different requirements.
The main features of eps pre-expander:
EPS pre-expander is to make raw material into beads. The EPS beads have many usages. They can make EPS blocks by block molding machine, they can also make boxes, eps icf blocks by eps shape molding machine, they can also make lightweight wall panels by eps concrete wall panel production line. They can also be used alone to make lying bags, etc.
For construction decoration:
For construction(3D panels):
For construction(icf blocks):
For wall insulation and roof insulation of buildings:
