accuracy,less steam consumption
--
Including stainless steel dryer bed, screw conveyer, filling, sieving device, etc
Steam system: Accurate pressure reducer and PID control system (proportional steam
valve system) to keep very stable and accurate steam, ensure material variation ;
Pressure control: Pressure sensor with multi-steam exhausting system to keep expansion chamber
pressure stable, Also reduce the steam consumption;
Temperature control: Adopts temperature sensor and compressed air proportional valve to keep accurate expansion temperature, which is suitable for high density expansion, less broken beads;
Material level control: Keeps accurate weighing scales and vibrated level sensor control, ensure less density tolerance.
Material filling system: Set filling weight in touch screen and electronic weighing filling to realize filling accurately and automatically;
Electric control: Adopts PLC and touch screen, electronic parts, valves are famous brand , which make the whole working procedure automatically and stable.
Note:
Auto density-weighing system is optional.
Secondary expansion device for SPJ130, SPJ160 is optional.
