Quality Components for Superior Results: The stainless steel dryer bed is equipped with a temperature control system that can heat up to 150°C for rapid drying. The screw conveyer's pitch and diameter are optimized for efficient material handling, with a conveying efficiency of over 90%. The sieving device is adjustable, allowing for different mesh sizes to be used depending on the bead size requirements.
Steam System Perfection: The accurate pressure reducer and PID control system of the accurancy batch polystyrene pre-expander machine can handle steam pressures up to 2 bar. The steam supply is regulated with a precision of ±0.02 bar, ensuring consistent expansion and minimizing material waste. The steam consumption is reduced by an average of 30% compared to conventional expanders.
Pressure Control at Its Finest: The pressure sensor in the polystyrene batch expander machine has a wide measurement range from 0.05 - 2 bar. The multi-steam exhausting system is designed to maintain a constant pressure within ±0.01 bar during the expansion process. This stability is essential for producing beads with a uniform density and size.
Temperature Control for Optimal Expansion: The temperature sensor is calibrated to an accuracy of ±0.05°C. The compressed air proportional valve can control the temperature with a resolution of 0.05°C, making it ideal for high-density expansion. This results in a reduction in broken beads and improved product quality. The temperature control equipment also recycles heat energy, further reducing overall energy consumption.
Material Level Precision: The styrofoam batch expander machine's weighing scales have a tare function for accurate net weight measurement. The vibrated level sensor has a frequency adjustment option, allowing for better adaptation to different material characteristics. The combination ensures a density tolerance of ±0.01 kg/m³.
Efficient Material Filling: The touch screen allows for easy programming of filling parameters. The electronic weighing filling system has a built-in self-calibration function, ensuring accurate filling within ±0.03 kg. The filling speed can be adjusted from 0.5 - 5 kg/min.
Reliable Electric Control: The PLC touch screen provides real-time monitoring and control of the entire machine operation. The branded electronic parts and valves have a long service life, reducing maintenance costs and ensuring continuous production.
The auto density-weighing system offers enhanced density control, especially useful for applications where strict density requirements are imposed.
The secondary expansion device for SPJ130 and SPJ160 provides an opportunity to create custom bead structures and densities, catering to specialized EPS product manufacturing.
