Possible materials :
PP, HDPE, LDPE, PET, PC film, Nylon fiber, PP carpet, Jumbo bag, EPE, EPP, EPS, etc.


How It Works :
①Conveyor ➜ ②Side shredder ➜ ③Extruder ➜ ④Water ring pelletizing system ➜ ⑤Centrifugal dryer ➜ ⑥Vibrating screening unit ➜ ⑦Storage tank

The conveyor is to deliver plastic wastes to the side shredder for crushing. The recycled plastic resources must be broken into small pieces before fed into the single screw extruder to avoid causing screw abrasion. The crushed pieces are melted, kneaded, and filtered by the extruder, then pass through the water ring pelletizing system to be cut into pellets. All the pellets are cooled, dried, and screened to become reusable materials.

  • Conveyor
    Conveyor is to deliver plastic wastes to side shredder for crushing into small pieces. Different specifications are available.

  • Side shredder
    The equipment is suitable for shredding light, fluffy, or foaming plastic wastes. The recycled plastics must be crushed into small pieces before fed into plastic extruder to prevent large fragments from causing overload and stop of the shredder cutter.

  • Plastic extruder
    Plastic extruder is to melt, deliver, knead, and filter plastics. The extruder screws and barrels are the key components. The design, material selection, and machining accuracy will affect the quality of the final finished pellets.

  • Water ring pelletizing system
    Water ring pelletizing system is widely used, but it is not suitable for sticky, low-viscosity materials because pellets can stick together before they hit the water. When the molten polymer exits the die holes and is cut into pellets by rotating knives in air. The pellets produced outwards are cooled by water and then transported to downstream centrifugal dryer.

  • Centrifugal dryer
    The equipment is located after pelletizing machine. It can eliminate surface moisture on the plastic pellets.

  • Vibrating screening unit
    The unit can filter out different sizes of pellets to ensure a good average quality.

  • Storage tank
    The storage tank is to store plastic pellets and it is made by stainless steel. Different sizes are available on request. Customers can also choose big bag filling machine or bagging machine.

1. Double degassing design
The double degassing design on our single screw plastic extruder is optional. It can process plastic wastes with high moisture content to sufficiently devolatilize moisture or gas to keep the purity of the melt.

2. High throughput
The CYKF self-designed extruder screws ensure high-throughput performance. The excellent mixing behavior of the screws can effectively reduce loss of material physical properties during production and maintain pellet quality. The pellets not only can be fed back to the original production cycle but also applied to wider usages.

3. High level of automation
The high-level human-machine interface intelligently integrates and controls each recycling process. The clear and simple operation interface helps operators analyze, monitor, and adjust production parameters at any time. The excellent safety warning system also brings safe working environment.

4. Durable and steady
Every piece of equipment made by CYKF can steadily run for over few decades. Thanks to our strict quality policy that makes our plastic pelletizing recycling machines continuously win trusts and praises from global customers.

5. Various options for customization
The CK-SC series has 4 models, which can be equipped with different pelletizing systems and auxiliary equipment. Please contact us immediately for more product information.
