La línea de granulación de espuma plástica es una solución diseñada para el reciclaje y granulación de espuma plástica. En los últimos años, la espuma se ha utilizado ampliamente en la industria del embalaje, pero es grande y difícil de transportar. Esto ha llevado al rápido desarrollo de maquinaria y equipos de recuperación y reciclaje de espuma. Con la adopción continua de nuevas tecnologías, la tecnología de los equipos y la eficiencia de producción de las máquinas de reciclaje de poliestireno expandido generalmente han mejorado rápidamente.
Introduction of Plastic Foam Pelletizing Line
The plastic foam pelletizing line efficiently recycles waste foam via compacting, crushing, heating, melting, extrusion, and pelletizing, which features high output, low energy consumption, stable operation, suitable for polystyrene, etc., turning scraps into reusable pellets to boost resource utilization and environmental protection.
Expanded polystyrene pelletizing machine for plastic foam recycling is an integrated industrial system designed to recycle waste plastic foam into reusable plastic pellets. This process transforms low-value, bulky foam waste into high-quality raw materials for new plastic production. The line typically combines mechanical crushing, thermal melting, and pelletizing technologies to achieve efficient material recycling, addressing both environmental pollution and resource scarcity challenges.

Process Flow of Plastic Foam Pelletizing Line
Trituración – aglomeración – estirado – enfriamiento – granulación
The plastic foam pelletizing line is 100% available for recycled foam. EPS EPE foam is compressed and then pelletized, making it the most widely recycled processing method. The foam is compressed or thermally melted by a professional foam compressor, which results in a compressed block. The shredded foam compressed blocks can be used for pelletizing to produce high-quality EPS EPE pellets. It can be applied to the production of new foam products. Now, with the growing popularity of carbon emission reduction, recycling has become the primary method for regenerating EPS.
There are some differences between EPE and EPS pelletizing in the EPE EPS foam granulating line. EPE foam is soft, and the granulator to process this kind of foam usually contains an automatic feeding device. Also, the EPE foam doesn’t need a crusher for pre-processing, so that it can be directly put into the granulator.
EPS foam is usually large size, which means EPS foam needs to be shredded by a crusher and compacted. As a result, this kind of foam can enter the granulator for processing.
Main machines of Plastic Foam Granulator Line
Plastic foam crusher
La trituradora de espuma plástica se utiliza para triturar grandes trozos de espuma reciclada en trozos pequeños que se pueden derretir y granular fácilmente.
Máquina compactadora de espuma
Due to the low density and large volume of the foam, it needs to be compressed by the foam compactor machine after crushing to improve the material transportation efficiency.
Extrusora de espuma plástica
La extrusora de espuma plástica se utiliza para fundir y extruir pequeños trozos de espuma plástica triturada en tiras largas.
Tanque de enfriamiento
El tanque de enfriamiento se utiliza para enfriar las tiras de plástico de alta temperatura para que se endurezcan y se puedan cortar fácilmente.
Cortador de gránulos de plástico
El cortador de gránulos de plástico se utiliza para cortar tiras largas de plástico enfriado y endurecido en gránulos de plástico de tamaño uniforme.

Raw Materials and Finished Products of Plastic Foam Pelletizing Line
La línea de granulación de espuma plástica puede producir gránulos de plástico a partir de residuos de espuma reciclados.
Polietileno expandido
El Polietileno Expandido es una espuma estructural hecha de polímeros de polietileno. Se fabrica calentando y comprimiendo el polímero de polietileno para formar burbujas de aire que lo hacen liviano, flexible y con propiedades de aislamiento acústico y térmico. Se utiliza principalmente en embalaje, construcción y aplicaciones domésticas.
Poliestireno expandido
El EPS, o poliestireno expandido, es un material liviano, rígido y termopar hecho de pequeñas bolitas de poliestireno. El EPS se utiliza comúnmente para aplicaciones de aislamiento, embalaje y acolchado protector debido a su bajo costo, versatilidad y buenas propiedades de aislamiento.
Para fabricar EPS, se mezclan pequeñas partículas de poliestireno con un inflador, como el propano, y luego se calientan y se moldean en bloques grandes. El inflador forma pequeñas burbujas dentro de los pellets, lo que hace que se expandan y formen un organismo. Dependiendo de la aplicación deseada, el proceso de expansión se puede controlar para producir EPS con diferentes densidades y propiedades físicas.

FAQs of Plastic Recycling Machine
What is the typical production capacity of the EPE， EPS Foam Granulating Line?
The plastic foam pelletizing line boasts a production rate of 200-250 kg/h, depending on your raw material.
If you would like more detailed information, please feel free to contact us.
Can wet foam be pelletized directly in the plastic foam pelletizing line?
No. Moisture causes bubbles in the melt and cracked pellets; it must be dried via hot air or centrifugal dehydration.
Why do pellets discolor?
In a plastic foam pelletizing line, possible causes may be extrusion temperature too high (plastic degradation), raw material contamination, or clogged filters. Check temperature control and clean impurities.
