The plastic foam pelletizing line is mainly used to recycle waste EPE/EPS foam, with the final product being recycled pellets. The entire plastic foam pelletizing line is equipped with a conveyor, foam melting machine, foam compactor, foam granulator, cooling tank, pellet cutting machine, and storage bin. The most important piece of equipment is the foam granulator, which melts and extrudes the plastic into long strips for further pelletizing. The output range of this plastic recycling line is 150kg/h-300kg/h.
Raw Materials and Final Products of Plastic Foam Pelletizing Line
The raw material for the plastic foam pelletizing line is mainly EPE foam (Expanded polyethylene) and EPS foam (Expandable Polystyrene).
EPE (Expanded polyethylene), also known as EPE pearl cotton, is a new type of environmentally friendly packaging material. EPE (Expanded polyethylene), also known as EPE pearl cotton, is a new type of environmentally friendly packaging material. It has many advantages such as water and moisture barrier, shockproofing, sound insulation, heat preservation, good plasticity, toughness, recycling, environmental protection, etc.
It is an ideal substitute for traditional packaging materials. Because of the special advantages, not only does not pollute the environment, and can be recycled repeatedly, so EPE pearl cotton is widely used in all walks of life. Examples include fruit netting, elastic lining for bags and luggage, acoustic and thermal insulation, etc.
EPS (Expandable Polystyrene) has the advantages of low relative density, low water absorption, heat insulation, sound insulation, moisture-proof, vibration damping, excellent dielectric properties, etc. It is widely used in machinery and equipment, household electrical, handicrafts, and other fragile and valuable products of shockproof packaging materials and fast food packaging.
Process of Plastic Foam Pelletizing Line
The waste plastic foam is first fed to the foam melting machine, which crushes and melts the foam into piles. The lumped plastic is then compressed into squares in the foam compactor and extruded into strips in the foam granulator. After being cooled in a cooling tank, it enters the pellet cutting machine, where the finished product is a uniformly sized pellet.
Equipment Introduction of EPS Foam Granulating Line
EPS Foam Melting Machine: This machine is an all-in-one foam-crushing and lumping machine. The foam melting machine is used to break up white foam waste such as foam fast food containers and insulated boxes. They are then pushed by a screw to the heating zone where, after being heated and plasticized, the plastic foam is squeezed into blocks.
Foam Compactor: The foam compactor is used to compress foam into cubes. After compression, the density of the foam increases, making it easier to transport and recycle.
Plastic Foam Granulator: The plastic foam granulator is used to melt the plastic foam and extrude them into strips. The machine uses EPE/EPS as raw material for extrusion pelletizing and the processed recycled pellets can be reused.
Cooling Tank: The cooling tank is used to cool and harden the long strips of plastic extruded from the foam granulator for pelletizing.
Plastic Pellet Cutting Machine: This machine is used to cut long strips of plastic into granules, the size of which can be adjusted.
Plastic Foam Granulator of Plastic Foam Pelletizing Line
There are two types of granulators for plastic foam pelletizing line, an EPS foam pelletizing machine, and an EPE foam pelletizing machine.
EPS Foam Pelletizing Machine
The EPS pelletizer is suitable for pelletizing EPS foam such as foam fast food boxes, packaging boxes, and insulation boxes. The EPS pelletizer consists of a main machine, auxiliary machine, die head and crusher, etc. It adopts a conical twin-screw barrel, which speeds up the filling speed and greatly improves the output.
EPE Foam Pelletizing Machine
EPE granulator for the granulation of waste foam and pearl cotton made of EPE. The EPE foam pelletizer includes the feeding system, the compacting and extrusion system, and the vacuum exhaust system. Due to the special characteristics of EPE foam, the barrel length of the EPE granulator is longer than that of the EPS granulator and is easily identified by its appearance.
EPS Foam Compactor of EPS Foam Granulating Line
There are two types of EPS foam compactor of plastic foam pelletizing line: vertical EPS foam compactor, and horizontal EPS foam compactor.
EPS foam compactor can easily compact foam and reduce the volume of plastic, effectively solving the problem of large size of EPS foam, recycling difficulties, and inconvenient transportation. The machine has a high compression ratio and can reduce the volume of plastic foam by up to 40 times. Compression without the addition of any other chemical materials.
