Pre-expanding machine

Keywords:
  • EPS/STMMA/STMMA-FD

1.      Description

The equipment including the automatic electronic weighing and quantitative feeding system, pressure chamber and computer control system, discharge system and drying bed; automatic electronic weighing and quantitative feeding system have top/middle/bottom silos, the top silo is for raw material, middle silo is for weighing, bottom silo is connect to charging valve; pressure chamber and computer control system is the main parts; discharge system and drying bed including the discharge fans/drying fans/filter/transport fans etc..

Produce:EPS/EPMMA/STMMA.


2.      Advantage

(1)The equipment is simple to operate, one-button start, full automatic ,front-line staff can also operate;

(2)The machine is wider practicability, It can produce different types of EPS and STMMA.

(3) It have good quality level, the beads size is stable,have low humidity,no die beads,no blocking..

5.      More detail

The produce: Prepare→ Charging→ Preheating → Heating→Exhaust→ Stabilization→ Discharge→ Waiting;

The preheating method can choose the control of temperature/time/material level. temperature control: 85℃-105℃ depend on the density; if the steam is stable, can choose the control of time/material level. Reduce pressure:2-3s。stabilization:20-30s,it will affect the humidity of beads. discharging:20-50s
