PP/HDPE Plastic Bottle Flake Recycling Machine
The machine in the video is SJ160/SJ180 double stage single screw extruder.
Its capacity can reach 1000kg/h.
To filter the sticky waste in bottle flake, machine get equipped with four hydraulic screens changing system.

General introduction:

The material is transported directly into the extruder by a spiral feeder. The rate of material feeding is controlled automatically by the current of the extruder motor and main extruder screw rotating speed. This design will keep material with balance feeding, and protect material from blocking and melting in the shredding compactor.

Degassing parts: natural degassing/ vacuum degassing

Melting plastic is filtered by a continuous melt filter (plate hydraulic screen filter, double volume screen changer) available with or without back-flushing system. According to material type, the pelletizing way can be equipped with a water ring, strand or underwater pelletizing system.
