HDPE Bottle Flakes Plastic Pelletizing Line

Raw Material

The catering device is chiefly appropriate for fragmented durable plastic scrap, encompassing HDPE, LDPE, PP, ABS, and various others. Additionally, this pelletizing system is capable of managing delicate pliable refuse, such as crushed PE film refuse, PP filament substance, PP / PE interlaced pouch, and PE foam substance. These components may be transmitted to the extrusion portion via a pressurized feeding mechanism for merging and liquefaction.

The advantages of core components

1. The tube of the granulator is produced from 45# forged steel with an alloy sleeve inserted (or entirely 38CrMoAlA nitride), which exhibits resistance to friction and erosion.
2. The auger is fashioned from alloy steel, having undergone vacuum quenching or nitriding, rendering it resilient.
3. The gearbox's output shaft bearing employs German INA bearings, while the spindle is made from specialized alloy materials that have been carburized, ensuring efficient, long-term stable operation.
4. The heating component is made of cast aluminum or cast copper electric heater, furnished with an insulation module for both energy efficiency and durability.
5. The electrical control system encompasses a Japanese RKC dual-channel PID digital intelligent temperature control meter, an INVT constant torque AC inverter, a vacuum exhaust unit, a soft water cooling system for the barrel, stainless steel water tank, dryer, granulator, and electrical control cabinet. 6. Furthermore, the granulation equipment can be fitted with a large flow plate screen changer with dual working positions and a mobile hydraulic station. Different auxiliary granulating machines can be configured according to various materials, resulting in diverse granulation lines, as indicated below:

Details of plastic pelletizing production line:

Feeding Device

The substance can be directly introduced into the extrusion segment using a screw feeder (or a belt conveyor feeder). The feeding speed is automatically modified by sensing the motor workload of the extruder and regulating the current ampere load in order to avoid excessive or insufficient feeding.

Extruder

The unit includes a gear reduction device(high torque, reduced noise, outer cooling cycle system), a nitriding 38CrMoA1 spiral, a tube(38CrMoAlA, nitriding, regulated by temperature control), and a vacuum system.

Melt filter screen changer system

Adequate, user-friendly filtration systems may be chosen based on the state of the raw materials, sifting impurities to guarantee the purity of the end product. Optional:
a. Laser filtration switch - automated scraping mechanism, decreasing cleaning and substitution frequency effectively;
b. Reverse flush sieve changer - self-cleaning mesh, notably cutting down filter replacement frequency, diminishing labor;
c. Twin piston large-scale sieve changer - automatic and hydraulic with expanded filter area;
d. Panel sieve changer - simple to operate, recyclable screen filter, cost-saving, suitable for rough and fine filtration.

Laser screen changer (optional for HDPE/PP regrinds 100micron)

Applications

PTJ filters are appropriate for handling common polyolefins and polystyrenes, excluding PVC, PVDC, EVA. They are intended to eliminate foreign objects like paper, aluminum, wood, elastomers (rubber, silicone), and high-melting polymer compounds from significantly impure materials.
