Purui - Model ML -PET Clean Bottle Flake Pelletizing Extruder
From shredding compactor, the material is transported directly into the extruder by a belt conveyor without being pre-cut or compressed. 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.
General introduction:
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.
- with double discs at shredding compactor, flakes get further mixed and dried.
- with specially designed vacuum system( separated vacuum venting), extruder can guarantee IV changing within 0.03.
- Underwater cutting system further improves melt PET cutting problem.
- The whole system get controlled by PLC touch screen, extruder realized automatic production.
