Hangzhou Epsole Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of eps continuous pre-expander polystyrene machine in China. We warmly welcome you to buy high quality eps continuous pre-expander polystyrene machine for sale here from our factory. Good service and reasonable price are available.
The EPS continuous pre-expander is a high-efficiency industrial machine designed for large-volume production of expanded polystyrene (EPS) beads. Unlike batch-type machines that operate in discrete cycles, continuous pre-expanders implement steady-state operation – raw EPS beads are continuously fed into the expansion chamber, expanded by steam, and continuously discharged into the fluidized bed dryer and aging silos. This uninterrupted workflow delivers substantial advantages for wholesale buyers: higher capacity (150–500 kg/h), consistent bead density, and reduced labor requirements for mass production of insulation boards and packaging materials.
Core Performance
Capacity and Production Efficiency
Continuous pre‑expanders maintain uninterrupted material flow, maximizing machine utilization time and delivering up to 24/7 production capability.
Foaming Density Range and Uniformity
The continuous pre‑expander uses precise steam pressure control and material feed rate regulation to maintain consistent bead expansion.
Continuous Foaming Process Principle
Continuous uses a rotating chamber; Residence time – Shorter and uniform in continuous; Suitability – Continuous excels at large‑volume production.
Automated Control System
The EPS continuous pre-expander is equipped with a PLC-based automatic control system that manages the entire continuous production workflow.
Fluidized Bed Dryer System
The continuous pre-expander is standard-equipped with a fluidized bed dryer that completes all post-expansion processing in a single automated step.
Steam Energy Saving Design
Continuous pre-expanders generally consume more steam than batch machines due to continuous heat loss from the rotating chamber.
