Why Our EPS Pelletizer?

High Volume Reduction

Significantly reduces EPS foam volume (up to 90:1), minimizing storage and transportation costs effectively.

Cost Savings

Lower landfill fees, reduced labor for handling waste, and creates a valuable secondary raw material.

Eco-Friendly Recycling

Diverts problematic EPS waste from landfills, supporting sustainability goals and producing recyclable PS pellets.

Efficient Hot-Melt Technology

Utilizes advanced hot-melt extrusion for dense, uniform pellets, ensuring high-quality output for reuse.

Robust & Reliable

Engineered for durability with high-quality components, ensuring long operational life and consistent performance.

Revenue Generation

The produced PS pellets are a marketable commodity, creating an additional revenue stream from waste material.

EPS Pelletizing Process

1

Material Feeding

Loose or pre-crushed EPS foam waste is fed into the machine’s hopper, often via a conveyor system.

2

Crushing & Pre-Compacting

An integrated crusher breaks down larger EPS pieces. A screw then compacts and pushes the material forward.

3

Heating & Melting

The compacted EPS is conveyed through a heated barrel, where it melts into a viscous polystyrene liquid.

4

Extrusion & Pelletizing

Molten PS is extruded through a die head and cut into small, uniform pellets by a high-speed pelletizer (e.g., water-ring or strand).

5

Cooling & Collection

Pellets are rapidly cooled (typically with water or air) and then dried, ready for bagging and storage.

Watch how our EPS foam pelletizing machine efficiently transforms voluminous waste into valuable, dense pellets.

Core Components of the Machine

Crushing Unit

Robust blades break down bulky EPS foam into smaller, manageable pieces for efficient feeding into the melting screw.

Hot-Melt Screw Extruder

Specially designed screw and heated barrel melts, homogenizes, and pressurizes the EPS material for extrusion.

Pelletizing Head & Cutter

Forms molten PS into strands or directly cuts it at the die face (e.g., water-ring pelletizer) into uniform pellets.

Cooling & Drying System

Rapidly cools the hot pellets using water or air, followed by a dewatering or drying stage to remove moisture.

Degassing System (Optional)

Vents to remove trapped air and moisture from the molten PS, improving pellet quality and density.

Control Panel (PLC)

User-friendly interface for controlling temperature, speed, and other operational parameters for optimal performance.

Frequently Asked Questions (EPS Pelletizing)

What types of EPS foam can this machine process? +
Our EPS pelletizing machines can process various forms of Expanded Polystyrene (EPS), including packaging materials, insulation boards, fish boxes (cleaned), and general EPS scrap. It can also handle similar foams like XPS and EPP with potential minor adjustments.
What is the typical volume reduction ratio? +
EPS foam is about 98% air. Our hot-melt pelletizing machines can achieve a significant volume reduction, often up to 90:1, transforming bulky foam into dense, easy-to-handle pellets.
What is the quality and use of the output pellets? +
The machine produces high-density, uniform Polystyrene (PS) pellets. These pellets are a valuable raw material for manufacturing new PS products like picture frames, hangers, construction moldings, and other injection-molded or extruded items.
How does this differ from an EPS cold compactor? +
A cold compactor uses pressure to squeeze air out of EPS, producing dense blocks or ingots. Our hot-melt pelletizer melts the EPS and then extrudes and cuts it into small pellets. Pellets are often preferred for direct use in manufacturing processes, while blocks might require further processing.
What are the power and space requirements? +
Power and space requirements vary depending on the model and capacity. Smaller units might require around 20-30 kW, while larger ones need more. We provide detailed specifications and layout plans upon inquiry for your specific needs.
Do you offer installation and after-sales support? +
Yes, we provide comprehensive support including on-site installation, commissioning, operator training, and ongoing after-sales service with spare parts availability to ensure smooth and continuous operation of your EPS pelletizing line.
