ABS / PC / PP Flake Pelletizing Line
ABS / PC / PP Flake Pelletizing Line
Raw Material
It is mainly suitable for crushed hard plastic waste, includes HDPE, LDPE, PP, ABS and other.
This pelletizing line can also deal with light soft waste, including crushed PE film waste, PP silk material, PP / PE woven bag, PE foamed material, etc. They can be sent to the extrusion section by a pressure feeding device to melt and mix.
rigid plastic flakes
Squeezed drying waste after washing
The advantages of core components
1.The barrel of the granulator is manufactured by 45 # forged steel inserted alloy sleeve (or the whole 38CrMoAlA nitride), which is friction and erosion-resistant.
2.The screw is made of alloy steel, have passed by vacuum quenching or nitride, it is durable.
3.The gearbox output shaft bearing uses German INA bearings, the spindle is made of special alloy materials, which has been carburized, ensuring high-efficiency and long-term stable operation.
4.The heater is made of cast aluminum or cast copper electric heater, equipped with an insulation module, energy saving and durable.
5.Japanese RKC dual-channel PID digital smart temperature control meter, INVT constant torque AC inverter, vacuum exhaust unit, soft water cooling system on barrel, stainless steel water tank, dryer, granulator, electrical control cabinet, etc.
6.The granulation equipment can also be equipped with large flow plate screen changer with double working position, a mobile hydraulic station, different granulated auxiliary machine can be set according to different materials, constituting different granulation lines, as shown below:

Details
Feeding structure
Material can be directly added to the extrusion section through a screw feeding device (or a conveyor belt feeding device). The feeding speed is automatically adjusted by detecting the load of the extruder motor and controlling the current ampere load to prevent excessive feeding or insufficient feed.
Extruder
It consists of a gear reducer (high torque, low noise, external cooling cycle system), a nitriding 38CrMoA1 screw, a barrel (38CrMoAlA, nitriding, controlled by temperature control ), and a vacuum system.
Melt filter screen changer system
Suitable easy-to-operate filtration systems can be selected according to the condition of the raw material, and the dirt is filtered to ensure the pureness of the final pellets. Optional：
a.Laser screen changer - automatic scraping technology, can effectively reduce the frequency of cleaning and replacement;
b.Backflush screen changer - automatic cleaning mesh, greatly reducing the frequency of the filter replacement, reducing labor;
c.Double-piston large-scale screen changer - larger filter area, automatic and hydraulic;
d.Plate screen changer - easily operate, screen filter can be recycled, save cost, suitable for crude filtration and fine filtration.
Laser screen changer(optional for HDPE/PP/ABS/PS regrinds 100micron)
Applications
PTJ continuous melt filters are suitable for processing all standard polyolefins and polystyrenes with the exception of PVC、PVDC、EVA; they are designed to remove foreign particles such as paper, aluminum, wood, elastomers (rubber, silicone) or high-melting polymer composites from heavily contaminated materials.
