      Pre-expander

              Automatic pressurized intermittent batch pre-expander is newly designed and made by our company, according to the latest international and domestic marketing requirements, used for first and second expansion. This type of EPS machine is an automatic expanding system, composed of pressurized batch pre-expander, fluidized bed drier, sieving, delumpling, screw conveyor and etc making an fully automatic cycle foam system. It is an essential machine for EPS factory.
          

              Expanded EPS beads through aging under normal pressure can be provided for EPS molding machine to make different shapes of packing products as well as different sized blocks. They are ideal packing materials for household appliance, gauges, instruments, chinaware, glassware and all sorts of valuable and fragile things. Blocks can be used in house construction, cars, ships,refrigerators etc, because they are good material of sound insulation, heat insulation and vibration proof.

      MAIN FEATURES
      1.The machine adopts PLC and touch screen, automatic filling, electronic weighing, temperature control, material level control to realize automatic production
      2.Machine is complete with Screw Conveyor and Electronic Weight system
      3.Closed expansion chamber enables expansion under constant pressure. high steaming efficiency and steam saving
      4.With proportional valves to control steam and air flow
      5.With photocell or vibration sensor to control material level. ensuring density tolerance within±3%
      6.The machine is equipped with fluidized bed dryer. including drying. automatic sieving, delumping and material conveying to silos
      7.Most components used in the machine are of famous brand both at home and abroad
