Accuracy、Less steam consumption
MAIN FEATURES
Including stainless steel dryer bed, screw conveyer, sieving device, etc
1.Steam system: Accurate pressure reducer and PID control system (proportional steam valve system) to keep very stable and accurate steam, ensure material variation;
2.Pressure control: Pressure sensor with multi-steam and exhausting system to keep expansion chamber pressure stably, also reduce the steam consumption;
3.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;
4.Material level control: Keeps accurate weighing scales and vibrated level sensor control, ensure less density tolerance.
5.Weighing filling: Set filling weight in touch screen and electronic weighing filling to realize filling accurate and automatically;
6.Electric control: Adopts PLC programmable controller and touch screen, electronic parts, valves are famous brand (Schneider touch screen and electronic, Mitsubishi PLC, Germany valves), which control the whole working procedure automatically and stably.

Note: 
• Auto density-weighing system is optional.
• Secondary expansion device for SPJ130, SPJ160 is optional.
