China auto eps pre-expander machine with less steam consumption

We use the advanced technology to manufacture SPJ50/90/130/160 batch EPS pre-expander machine-A(Accuracy), It is applied to  EPS foaming, The EPS polystyrene pre-expander machine has enhanced the production efficiency and improved the foaming quality. High-quality batch EPS pre-expander machine also makes expansion of the EPS beads more accurate, lighter, faster, as well as reliable operation with low faulty rates.


Main Features:

Our batch EPS pre-expander machine includs stainless steel dryer bed, screw conveyer, filling, sieving device, etc. It is a complete pre-expander equipment.

Steam system: Accurate pressure reducer and PID control system (proportional steam valve system) to keep very stable and accurate steam, ensure material variation. The pressure inside the EPS polystyrene pre-expander machine is throughout stable, ensuring the error of bead foaming is within ±2%.

Pressure control: There is pressure sensor in the pre-expander equipment, the pressure sensor with multi-steam exhausting system to keep expansion chamber pressure stable, as well as reduces the steam consumption.

Temperature control:The temperature sensor and compressed air proportional valve maintains accurate expansion temperature, which is suitable for high density. The hot air drying system of the batch EPS pre-expander machine, with temperature going up to suitable temperature will make the EPS beads dry up very quickly, shap fast, speed up the aging process and shorten the production process expansion, resulting in less broken beads.

Material level control: Keeps accurate weighing scales and vibrated level sensor control, to avoid inaccurate and unreliable readings due to the vibration produced during the operation process of the EPS pre-expander machine, ensuring less density tolerance.

Material filling system: Set filling weight in touch screen and electronic weighing filling to make the batch expander machine realize filling accurately and automatically.

Electric control: The PLC touch screen, electronic parts and valves are from reputed brands, which make the whole working procedure of pre-expander equipment automatic and stable.

 

Notes:

❉ Auto density-weighing system is optional.

❉ Secondary expansion device for SPJ130, SPJ160 is optional.
