The plastic pelletizing machine also known as plastic granulator, is mainly used for processing industrial and agricultural waste plastics. With special screw design and different configurations, plastic pelletizing machine models include single-screw plastic granulator, conical twin-screw plastic granulators, parallel twin-screw granulators. The plastic pelletizing machine is suitable for most common waste plastics range from PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA and other plastic regeneration and color mixing granulation. Recycled pellets can be reused again to make new plastic products. As the most widely used and most popular plastic recycling machine in the waste plastic recycling industry, granule-making machines can both create significant economic benefits and optimize resource allocation to protect the environment.
The main engine of the plastic granulator is an extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. The auxiliary machines of the plastic pelletizing machine unit mainly include pay-off device, straightening device, preheating device, cooling device, traction device, meter counter, spark tester, and wire take-up device.
The main sections of whole plastic pelletizing equipment involve Belt conveyor with metal detector/Force feeder/Compactor/Main extruder with degassing/Second extruder/Hydraulic screen changer/Die face cutting system/Water cooling tank/Dewatering machine/Vibrator screen/Packaing system.
The extrusion system includes a hopper and a die, and the plastic is plasticized into a uniform melt through the extrusion system.
The transmission system is used to drive the screw. The torque and speed required for the screw supply during the extrusion process generally consists of a motor, a reducer and a bearing.
Heating and cooling systm is necessary conditions for the plastic extrusion process to proceed. The heating device heats the plastic in the cylinder externally to heat it up to the temperature required for the process operation. The cooling device is set up to ensure that the plastic is in the temperature range required by the process
The physical properties of plastics are changed by high temperature melting, plasticizing and extrusion to achieve plasticizing and molding of plastics.

1. Automatic feeding according to customer requirements.
2. In the patented crushing/cutting compaction chamber, the plastic material is cut, mixed, heated, dried, densified and buffered by rotating rapidly blades.
3. The tangentially connected extruders are filled continuously.
4. In the extruder screw, the plastic material is extruded.
5. In the degassing zone: air and water etc. are volatile.
6. The plastic material is extruded to a die and pelletizer.
Side feeding is a stable, continuous feeding method. Overloads and underloads are avoided, thus guaranteeing maximum efficiency.
Hopper feeding is a flexible feeding method, without preheating, both soft and hard plastics can be processed
