Are you struggling to feed lightweight EVA foam sheets into your current recycling line? You are not alone.
For many recyclers, EVA foam (Ethylene Vinyl Acetate) is a difficult material. Its low bulk density and high volume make it nearly impossible for standard extruders to “grab” and process efficiently. The result? Bridging in the hopper, unstable throughput, and pellets filled with air bubbles.
At Rumtoo, we understand that efficiency is your bottom line. That is why we engineered the ML Series Cutter Compactor Pelletizing Machine—a game-changer designed specifically to handle “fluffy” plastics like EVA foam, transforming waste into uniform, high-density granules.
Why Standard Machines Fail with EVA Foam
Traditional single-screw extruders rely on gravity feeding. However, EVA foam strips and sheets are too light to fall naturally into the screw. They float, clog, and waste your energy.
To recycle EVA successfully, you don’t just need an extruder; you need a system that densifies the material before it melts.
The Solution: Rumtoo ML Series with Compacting Technology
Our Cutter Compactor Pelletizing Machine (ML Series) is the ultimate solution for soft plastic recycling. It integrates three critical steps into one compact unit:
1. Crushing & Densifying (The Heart of the System)
Instead of a passive hopper, our machine uses a high-speed Cutter Compactor at the inlet. When you feed EVA foam sheets into the machine:
- Rotary Knives cut the material instantly.
- Friction Heat pre-warms and shrinks the foam, significantly increasing its density.
- Result: The voluminous foam becomes a heavy, flowable material ready for extrusion.
2. Force Feeding for Stability
Forget about feeding interruptions. The centrifugal force generated by the compactor actively forces the densified EVA directly into the extruder screw. This ensures your production line runs at maximum capacity, 24/7.
3. Vacuum Degassing for Quality
EVA materials often trap gas and moisture. Our specialized Vacuum Degassing System removes volatiles during the melt phase, ensuring your final pellets are solid, glossy, and bubble-free—perfect for high-end reproduction.
Handling Heavy Duty Waste? The Shredder Advantage
While the ML Series is perfect for foam sheets and production scraps, some recycling centers deal with massive EVA lumps, thick purgings, or hard start-up waste. These heavy materials can damage a standard compactor.
For these tough challenges, we recommend starting your line with the Rumtoo Single-Shaft Shredder.
Our Single-Shaft Shredder acts as the powerful “first line of defense.” It breaks down large, solid blocks into manageable uniform chips.
- High Torque: Easily shreds thick materials that would stall other machines.
- Smart Protection: Equipped with Siemens PLC and Auto-Reverse technology to prevent jamming.
The Perfect Workflow:
Use the Single-Shaft Shredder to reduce large lumps ➡️ Feed the chips into the Cutter Compactor Pelletizer ➡️ Get premium pellets.

Frequently Asked Questions (FAQ)
Q: Can this machine handle printed EVA foam?
A: Yes. The ML Series is excellent at handling heavily printed materials. The vacuum degassing system effectively removes ink volatiles, and our dual-piston screen changer filters out impurities continuously.
Q: What is the moisture tolerance?
A: The friction heat in the compactor naturally dries materials with up to 5% moisture. for wetter materials, we can integrate a squeezer dryer into the line.
Q: How do I know which model fits my capacity?
A: We offer models ranging from 100kg/h to 1000kg/h. Contact our engineering team, and we will calculate the perfect size based on your specific material volume.
