EPS Batch Pre-expander is a versatile machine used in the manufacture of Expanded Polystyrene (EPS) foam products. This equipment is designed to pre-expand polystyrene beads with the aid of steam and air, thereby increasing their volume and reducing their density. The pre-expanding process is essential to create foam products that are lightweight, durable, and offer excellent thermal insulation properties.

EPS Batch Pre-expander is equipped with a specially designed screw conveyor and a steam generator system that facilitates the pre-expanding process. The polystyrene beads are fed into the machine hopper, and the screw conveyor transports them to the steam chamber, where they are treated with steam and air. This process causes the beads to expand, and the expanded beads are then discharged into a storage silo where they cool and await further processing.

The EPS Batch Pre-expander machine comes in various sizes, from small table-top machines to large industrial models for high-volume production. It is easy to operate, and the parameters can be easily adjusted to cater to various pre-expanding requirements. For example, the steam pressure, temperature, and flow rate can all be adjusted, depending on the type of polystyrene beads being used and the desired output.

EPS Batch Pre-expander is an energy-efficient machine that comes with a highly efficient steam generator system. It reduces the energy consumption in the pre-expanding process and provides precise control, resulting in better-quality foam products. The machine is easy to maintain, and the spare parts are readily available.

The EPS Batch Pre-expander machine is highly reliable, and it ensures consistent foam quality and output. The pre-expanded beads are used to produce a wide range of EPS foam products, such as insulation panels, packaging materials, and various foam products. With its flexibility and high productivity, EPSBatchPre-expander is an ideal machine for small to large-scale manufacturers of EPS foam products.

 Main features

1. EPS Batch Pre-Expander adopts imported dedicated weighing controllers, controlled by PLC and touch screen, to measure the foamed beads' weight accurately and provide timely feedback. It controls the foam density by adjusting the raw material feeding weight.

2. The drying system adopts a hot air curtain drying method. Compared with the traditional air chamber coiled tube type fluid bed drying method, the hot air curtain drying method heats the air chamber evenly. After stopping, the heat ceases, preventing fluid bed agglomeration.

3. Main valves, controls, and inspection components are imported from famous brands, ensuring energy efficiency and technological stability.

4. Steam inlet and cooling air inlet are controlled by PID valves. This allows for adjustable mixed steam temperature and pressure, ensuring accurate heating and even foaming. Discharge is also adjustable to meet different density requirements for steam temperature and pressure.

5. The level control system uses a Germany-imported vibration level sensor to accurately perceive the foaming bead rising degree. It controls the foaming level precisely, maintaining minimum foaming density tolerance for uniform foamed beads density.

6. The weighing system utilizes renowned brand dedicated weighing controllers and load cells, controlled by PLC and touch screen to accurately regulate raw material feeding weight, minimizing feeding tolerance.

7. The system includes steam pressure, compressed air pressure, and pressure inspections for the inside of the foaming barrel and drying barrel. It also monitors steam and foaming barrel temperatures, enhancing control over technology adjustments for different densities.

8. The shaft sleeve under the main shaft and guide sleeve of the discharging hole use graphite self-lubricating sleeves, eliminating the need for additional oil.

9. The feeding system employs a closed-air aspirator to expedite feeding without interference from the feeding fan.

10. It features a Siemens control system, utilizing advanced and reliable PLC and touch screen technology. The humanized man-machine interface dialogue ensures a reliable and aesthetically pleasing control system.
