EPS Pre-Expander is dedicated device of EPS raw material pre-expanding. Its full name is Multi-purpose Expandable Polystyrene pre-expander. It is to process expanding of EPS beads or second and more time expanding on the basis of first expanding. That is to feed EPS beads into equipment by first-time or second-time feeding entrance, and control the internal temperature of equipment by operating regulating valves on control panel so as to control the density of EPS beads.
