The EPS foam granulation line consists of five main single machines: plastic foam crusher, plastic foam extruder, cooling tank, EPS pellet cutting machine, and storage bin. It is a plastics solution designed for EPS foam recycling and the end product is plastic pellets with a production capacity of 100-500 kg per hour.
The EPE pelletizing process is slightly different from EPS, which we will introduce for you in detail next.
What Foams Can Be Pelletized?
Various types of foam materials can be pelletized, including expanded polystyrene (EPS), expanded polypropylene (EPP), and expanded polyethylene ( EPE). These foams usually include pearl wool, insulated boxes, disposable foam lunch boxes, foam cushions, foam packaging materials, foam fillers, etc.
By pelletizing these foams, they can be transformed into small, uniform pellets that are easier to handle, store, and reuse in the manufacturing of new products.
End Product – Foam Pellets
Expanded polystyrene recycling lines process waste foam material into high-quality plastic pellets. EPE and EPS pellets have a wide range of applications and can be reused to produce a variety of packaging materials, thermal insulation materials, filler materials, etc.
EPS Foam Granulation Process
The first step of EPS granulation is crushing, due to the large size of EPS foam, it needs to be crushed first to enter the granulator. The crushed foam blocks are transported to the hopper through the pipeline and then into the foam pelletizer to ensure that the material enters the granulation process smoothly.
The second step in foam recycling is to put the crushed foam blocks into a foam granulator for granulation. Here the foam is melted and extruded into plastic strips.
The third step is to put the plastic strip extruded into the cooling water tank to cool down and cure. The extruded plastic strip is too hot and soft to cut, so it must be cooled down first.
The fourth step is to cut the cooled plastic strips into uniformly sized plastic pellets using a pellet cutter machine. Finally, the plastic pellets are loaded into the storage bin.
EPE Foam Pelletizing Process
Unlike EPS granulating, EPE material can go directly into the pelletizer, this is because EPE material is softer and the EPE foam granule machine comes with a feeding device to shred it. The subsequent steps are the same as for EPS pelletizing, the long plastic strips extruded from the pelletizer are cooled and cut into small pellets.

Recommended EPS Foam Compactor
The lightweight and expandable nature of EPS foam materials results in a large amount of space being taken up during foam recycling and storage. This is also a major problem in EPS foam recycling. To solve this problem, we recommend the use of a specialized foam compactor. It compresses the foam material and reduces its volume, thus reducing the cost of storage and transportation.
Shuliy can offer two different types of foam compactors, a foam melting machine, and a foam compactor machine for you to choose from. They both perform the same function of compressing foam and reducing its volume. The difference is that one requires heat and the other is purely physical compression.

In addition to pelletizing, we offer other EPS recycling solutions. For example, EPS is melted and extruded into ingot blocks using an EPS hot melting recycling machine, or EPS foam is compressed into blocks using a foam compactor. Both methods are effective in reducing the volume of EPS foam for storage, transportation, and subsequent processing. Our company can provide the right solution for your needs and offer customized services to ensure that your specific requirements are met.
