Full Automatic Pressurized batch Pre-expander 1. The Material dosing & weighing unit guarantees consistency in material volume by using a load cell and indicator.
2. A level master sensor controls the level of expanding material and density variations of expanded beads to ±1%.
3. Fluid bed dryer evaporates bead moisture and prevents thermal shock.
4. In case of power faliure during the expansion cycle, steam is cut off and air is automatically applied to the
The quality level of EPS product largely depends on expanding process of EPS beads. Even flow of saturated steam into the expanding vessel leads to homogenous bead size distribution in the pre-expanded beads. And SUNGHOON pre-expander is controlled through high-performance PLC.
expander chamber in order to prevent bead lumping.
5. Operator-friendly Touch Screen Control system allows you easy operation as well as self-error checking, alarm,
