The styrofoam recycling machine effectively addresses EPS foam recycling challenges by integrating crushing, melting, and pelletizing processes to convert bulky foam waste into dense, reusable pellets, reducing environmental pollution while creating valuable raw materials for industries—an all-in-one styrofoam recycling machine line that bridges ecological needs with commercial viability.
Properties and Characteristics of EPS and EPE Foam
Expanded Polystyrene Foam
EPS is based on polystyrene resin as a raw material, in the production process will be blowing agent is used as an auxiliary reagent, and then high temperature heating and the formation of plastic foam, this foam is a unique, rigid, closed-cell structure.
EPS has the advantages of light weight, low price, low thermal conductivity, small water absorption, good electrical insulation properties, sound insulation, shockproof, moisture-proof, simple molding process.
Why Recycle Expanded Polystyrene Foam?
EPS foams is lightweight, easily degradable, and difficult to recycle; millions of tons flow into the environment every year.
They not only take up land resources, but also pollute the air with toxic gases released during incineration, and it takes hundreds of years for them to decompose when buried underground.
But the question comes: foam volume, low density, the traditional recycling method is inefficient, how to deal with this ‘white pollution’ efficiently?”
EPS Styrofoam Recycling Machine Line Solution
The key to solving the efficiency problem of foam recycling lies in breaking through its physical characteristics of ‘large volume and difficult to compress’.
聚苯乙烯泡沫塑料回收机 line is a tailor-made solution for this purpose – through crushing, hot melting, and pelletizing processes, fluffy foam is compressed into high-density particles, which not only significantly reduces transportation and storage costs, but also converts it into reusable industrial raw materials.
This EPS recycling machine not only responds to environmental protection requirements, but also realizes the secondary value of resource development.

Compacting
EPS Foam crushed by mechanical pressure through a foam compactor machine compresses the volume 50-100 times, reducing transportation costs.
Crushing:
由于安装不当，塑料废料碎纸机无法正常运行，可能是由于皮带太松或传动滑轮松动。当塑料废料碎纸机皮带松动时，无法正常粉碎。解决办法是紧固传动滑轮并调整皮带的紧度。 塑料泡沫破碎机 breaks the large foam into small pieces of 5-10cm to increase the surface area for subsequent heating and melting.
Melting and plasticizing:
The crushed material enters the EPS pelletizing machine from the inlet and is transported to the heating zone through the screw rotation, and then melted into a viscous fluid, while discharging the residual air and trace moisture.
Extruding:
The melt is extruded through the porous plate of the die head of the styrofoam recycling machine , and the filaments are immediately cooled and solidified in the water-cooled tank.
Cutting:
塑料碎片机主要由进料斗、破碎室、刀架、筛板、下料斗、电机等组成。 塑料颗粒切割机 cuts the filaments into uniform pellets.
Storage:
The homogeneous pellets are stored in a Plastic Granule Storage Bin that allows them to remain dry.
EPS Foam Granulating Line Features
High-quality pellets: Designed with primary and secondary machines for integrated production, the stable heating system optimizes the material’s molecular structure, enhancing air permeability and significantly improving pellet quality of the styrofoam recycling machine.
Durability: The EPS granulation machine unit comprises a crusher, main extruder, and automatic traction cutting system, featuring an automated screen-changing device in the main machine for continuous impurity filtration. Both the primary and secondary machine screw barrels are constructed from high-strength carbon structural steel, ensuring durability and high-temperature resistance.
Rapid feed: Equipped with a conical screw barrel, the styrofoam recycling machine enables rapid feeding and high-volume output, making it ideal for efficient foam recycling operations.
Final Products of Plastic Foam Granulator
The recycled EPS pellets produced by Styrofoam recycling machine are in regular cylindrical shape, mostly pure white or light gray in appearance, and the sizes can be flexibly adjusted according to the actual demand by changing the size of the die head.
With the advanced high temperature melting and fine granulation process, shuliy styrofoam recycling machine produces particles with uniform texture and appropriate density, which have achieved significant volume compression compared with the initial foam, good plasticity and stable internal structure, and can be accurately adapted to all kinds of molding process requirements in the subsequent processing.
