Batch Pre-expander Machine

    We supply complete eps foam production line and turnkey project. We can upgrade the machines according to customers’ requirements. Our company floor area 18000 square meters, has four big modern workshops.MAIN FEATURES: 1．This machine adopts PLC programmable controller and touching screen to carry out automatic production from feeding, temperature control, ration, pressurizing and feeding.2．Top-grade sealing foaming with constant pressure, high thermal efficiency, save 50％ steam or above than continuous foaming machine3．Adopt high-precision imported pneumatic control valve so that temperature can be controlled at ±1％, EPS grains are at same level with low water content.4．Correct feeding method can assure even density.MAIN SPECIFICATIONS & PARAMETERS: ◆ Expansion vessel: Ф1100× 1500(h)◆ Density range:  10～ 60kg/m3◆ Production efficiency: 150-300 Kg/h◆ Steam pressure:  0.4～ 0.8 Mpa◆ Compressed air pressure:  0.6～ 0.8 Mpa◆ Inlet of steam: 50mm◆ Inlet of compressed air: 50mm◆ Steam consumption: 6-10 Kg/cycle◆ compressed air consumption: 0.5-0.9 m3/cycle◆ Machine weight:  approx. 2500kg◆ Overall dimension: 1800*2200*4600mmTechnical Parameters of Polystyrene EPS Foam Pre-expander MachineModelPSJ-800PSJ-1100PSJ-1200PSJ-1400Vessel Size800×1200mm(h)1100×1500mm(h)1200×1500mm(h)1400×1700mm(h)Product Density13-60kg/m³13-60kg/m³13-60kg/m³13-60kg/m³Production Capacity60-100 Kg/h150-300 Kg/h200-400 Kg/h260-500 Kg/hSteam Pressure0.4-0.8 MpaAir Pressure0.6-0.8 MpaSteam Inlet Dia.50mmAir Inlet Dia.50mmSteam Consumption6-10 Kg/cycle6-10 Kg/cycle6-10 Kg/cycle10-15 Kg/cycleAir Consumption0.5-0.9m³/cycle0.5-0.9m³/cycle0.5-0.9m³/cycle1.3-2.8m³/cycleWeight1600kg2500kg2500kg3000kgOverall Dimension1800*1300*3000mm1800*2200*4600mm1800*2200*4600mm1900*2200*4600mmApplicationEPS Pre-expander Machine operation video
