Optimized Component Configuration: The stainless steel dryer bed has a perforated surface for better air circulation. The screw conveyer has a helical flight design for gentle material handling. The sieving device has a self-aligning mechanism for easy installation and replacement.
Steam System Mastery: The accurate pressure reducer and PID control system of the accurancy batch polystyrene pre-expander machine can maintain a steam pressure stability of ±0.025 bar. The steam supply is synchronized with the material feeding rate, ensuring efficient expansion. The steam consumption is reduced by about 31% compared to traditional expanders.
Pressure Control for Uniform Expansion: The pressure sensor in the polystyrene batch expander machine has a built-in alarm function for pressure deviations. The multi-steam exhausting system is designed to handle sudden pressure changes, maintaining a stable pressure within ±0.015 bar. This is essential for producing beads with a consistent density and spherical shape.
Temperature Control for Ideal Results: The temperature sensor has a linearity error of less than ±0.04°C. The compressed air proportional valve can adjust the temperature with a high degree of accuracy, minimizing broken beads. The temperature control equipment also has a heat recovery system to reuse waste heat, reducing energy costs.
Material Level Control Accuracy: The styrofoam batch expander machine's weighing scales have a digital filter function for noise reduction. The vibrated level sensor has a non-contact sensing principle, reducing wear and tear. The density tolerance is within ±0.013 kg/m³.
Accurate Material Filling: The touch screen has a graphical user interface for easy operation. The electronic weighing filling system has a tare and gross weight display for better material management. The filling accuracy is ±0.025 kg, and the filling rate can be adjusted from 0.8 - 6 kg/min.
Reliable Electric Control: The PLC touch screen has a data logging function for production record keeping. The branded electronic parts and valves are resistant to environmental factors, ensuring stable operation in different conditions.
The auto density-weighing system provides detailed density analysis and control, enabling the production of high-quality EPS beads.
The secondary expansion device for SPJ130 and SPJ160 offers the flexibility to create beads with complex internal structures, enhancing the performance of EPS products.
