Product Details

PE, PP Pelletizing Line Description:

The production line adopts European design and advanced technology. It is mainly used for clean PE PP films, scraps and crushed, washed, dried HDPE/LDPE/PP/PS materials. The material is sent to the compactor cutter through the conveyor belt, and fed into the single screw extruder by high speed rotation of the compactor cutter;

The screw is specially designed for cutting and compacting plastics. It has the advantages of fast feeding, wear resistance, etc., with natural exhaust and vacuum system; It can effectively remove the moisture inside the material; this extruder uses ceramic heating ring, durable and easy to maintain.

Compactor cutter can effectively dry materials, agglomerate, friction self-heating, high-speed forced feed into the screw after the material reaches a certain temperature, improve the output and reduce the heating of the screw to the plastic, accelerate the plasticization process; effective Energy savings;

Hydraulic screen changer is installed on the extruder die-head to effectively remove the impurities in the material; different quality of the finished product can be produced through the use of different mesh filters;

The special design of the extruder head part can effectively remove the hidden moisture inside the material and improve the granulation quality;

It can also be equipped with two stage granulation system, using two extruders to pass the material through secondary filtration, making the produced particles cleaner and higher quality;

It also can be equipped with a vibrating screen to sort out unqualified products; making the product particle size uniform and nice looking. The follow-up pelleting type can choose to strand/noodle pelletizer, or die face cutting (water ring pelletizer) to save labor and reduce waste;

The production line can be specially designed according to the cleanness of the customer's raw material and the quality requirement of the final product;

Energy Saving of Plastic Pelletizing Machine

Energy saving of plastic pelletizing machine can be divided into two parts: one is power part, another is heat.
Energy-saving power parts mostly adopts frequency converter by saving more energy of motor. For example, the real power of the motor is 50 hz, and in fact, 30 hz is enough in production. While that extra energy is wasted, the inverter is to change the motor power output in result of energy saving.
Energy-saving heating parts mostly adopts USES electromagnetic heater to save energy, and its energy saving rate accounts for about 30% – 70% of old-fashioned resistance.

1. Compared with the resistance heating, electromagnetic heater also has a layer of insulation to increase heat energy utilization rate.
2. Compared with the resistance heating, electromagnetic heater is directly related to feed tube heating, in order to reduce the heat transfer heat loss.
3. Compared with the resistance heating, electromagnetic heater speed is faster more than a quarter to reduce the heating time.
4. Compared with resistance heating, with fast speed of electromagnetic heater, production efficiency raises to make the motor in a saturated state, and it also reduces the electric energy loss because of high power and low demand.
The above four points are the reasons why electromagnetic heater can save 30% on plastic pelletizer.
