Eliminates “bridging” in the hopper caused by light, fluffy EVA foam.
High ROI
Turns 100% of your production waste back into raw material for new products.
Eficiência Energética
3-in-1 design (Shredding, Compacting, Extrusion) reduces power consumption.
The Process: How It Works
Recycling EVA foam requires a specific engineering approach due to its expansion properties. Here is our proven 3-step workflow.
Primary Size Reduction (For Bulky Waste)
Processing large EVA blocks, thick sheets, or baled agglomerates starts here. Before the material hits the extruder, it must be reduced to manageable sizes to ensure a consistent flow.
Equipamento recomendado:
Triturador de eixo único de material macio ou Triturador de eixo único para resíduos de cabeça de extrusora.
- Anti-Winding Rotor: Specifically designed to prevent flexible EVA strips from wrapping around the shaft.
- Controle Inteligente: Auto-reverse function detects overload and protects the motor.
Compacting & Densifying (The Core Technology)
This is where standard recyclers fail, but our system excels. Lightweight foam is difficult to feed directly into an extruder screw. Our integrated compactor uses friction heat to semi-plasticize the foam, drastically increasing its density.
Equipamento recomendado:
Máquina trituradora e granuladora integrada
Extrusion, Degassing & Pelletizing
The densified EVA material enters the extruder. Our specialized screw design ensures gentle melting to preserve the material’s physical properties (like elasticity). Vacuum degassing removes moisture and ink volatiles.
- Filtração: Hydraulic screen changer removes impurities continuously.
- Die-Face Cutting: Water ring pelletizing ensures pellets are cooled immediately, preventing them from sticking together.

Perguntas frequentes
Can this machine handle cross-linked EVA foam?
Yes, but it depends on the cross-linking degree. For heavily cross-linked materials, we recommend our specialized Heavy Duty Single Shaft Shredder first to reduce size, followed by testing in our facility to determine the optimal extrusion temperature.
Do I need a separate crusher?
Not necessarily. Our Integrated Shredder and Granulator system combines the crushing, compacting, and pelletizing steps into one machine, saving floor space and energy.
