Features of EPS Continuous Pre-expanders:
1. EPS beads enter the fluidized beds (optional) through charging material and expansion , then go into the aging silo through transporting fan to finish their auto –cycle expansion.
2. feeding system includes the first and second feeders.
3. Photoelectric switch controls the level of material in the auto-feeder of negative pressure to realize auto feeding (optional).
