Weifoer batch EPS Expander

 Including expansion body, dryer bed, automatic feeding system, sieving devices, weighing system, blower, etc.

Main advantage:

1. Fully automatic and intelligent prodcution;

2. Human-machine cooperation, controlled by PLC and color touch screen, easy to operate;

3. Accurate density, high output and energy-saving

4. Smooth operation and stable


Function Description:

Steam system:

Accurate pressure reducer 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, as well as reduces the steam consumption.

Temperature control:

The temperature sensor and compressed air maintains accurate expansion temperature, which is suitable for high density expansion, resulting in less broken beads.

Material level control:

Keeps accurate weighing scales control, ensuring less density tolerance.

Material filling system:

Set filling weight in touch screen and electronic weighing filling to realize filling accurately and automatically.

Electric control:

The PLC touch screen, electronic parts and valves are from reputed brands, which make the whole

 a---EPS pre-expander: it is used to expand the eps raw material to foamed beads; by second expansion, getting the lower density material and making

      the light eps foam block.
