Batch pre-expander


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, which control the whole working procedure automatically and stably.
