Plastic bottle flake pelletizing line is applied in PET waste flakes pelletizing field.The pellets are widely used in plastic industry.
Plastic bottle flake pelletizing line is applied in PET waste flakes pelletizing field. Through extrusion, cutting and dry process, the waste bottle will become to be pellets.The pellets are widely used in plastic industry, like sheet, and profile production.
In order to recycle waste plastics, waste plastic need to be washed, dried then melted, plasticized, extruded into strips, cooled by cooling system, and cut into granules by granulator. These granules are further processed into various plastics products by blowing, injection and calendering.
1) Single stage extruder and double stage extruders can be used according to user’s requirement or material condition.
2) Plastic pelletized polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (pvc), PET, HDPE, ABS and other engineering plastics or general plastics recycling and granulation.
3) Granules cutting type: water ring face cutting, strip/noodle type cutting and hot cutting;
4) Waste woven bags and waste film can be directly put into the granulation line without crushing.
5) The main engine is equipped with full automatic control cabinet and PLC operating system. It is easy to operate and has stable performance.
6) Low energy consumption, remarkable energy saving effect, high output, mechatronics.

Extruder
A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content.
Noodle Cutter Strand Type Cutting System
The length of the sink is 4 meters, which can be adjusted up and down, and the stainless steel pipe is designed to change water.
The sink is made of 2mm thick stainless steel plate.
Vibration Drying System
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption.
