1. Aging Silo Hopper (Fabric Filter Bag + Conical Bottom)
Receives pre-expanded EPS beads from the SPJY pre-expander discharge. Conical bottom design ensures complete bead flow without bridging. Each fabric silo holds 5-30 m3 (configurable) and provides 4-12 hours aging time for moisture release + pressure equalization.
Polyester or polypropylene breathable filter fabric (300-500 g/m2) supported by Q235B steel grid frame (40x40 mm). Top inlet flange DN150-200 mm. Conical hopper bottom (60-degree slope) with DN100-150 mm discharge flange + slide-gate valve. Volume options: 5 / 10 / 15 / 20 / 25 / 30 m3 per silo. Modular design — operator can add silos as production scales.
