Purui - Model ML130/SJ130 -PP Bag Recycling Machine
ML130/SJ130 pull strip pelletizing line /PP big bag recycling machine. Capacity:400kg/h . Screw diameter:130mm/130mm.
General introduction:
From shredding compactor, the material is transported directly into the extruder by a belt conveyor without being precut 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.
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.
How it works:
- Screw charger uploading material by timer
- Feeder and extruder is controlled by inverter
- Various L/D for Various material
- Natures degassing, vacuums degassing adopting for moisture
- Water ring die face cutting for perfect pellets shape
No need pre-heating and pre-cutting or other treatment of the material before extrusion.
It avoids the plastic precutting, the plastic bags and films and stretches can be fed directly in to the cutter compactor then crush, compress and heat, then it will go to the screw for plasticizing
Some washed 5-8% films can be feed directly, as it will be heated and dry in the compactor, then it will be degassed twice in the screw while plasticizing
Special designed screw and barrel, with experienced engineering we can offer and design for you the best screw and barrel to make the end pellets qualified
Cutter compactor:
As the conveyor directly connects with the compactor, the materials can follow the belt to cutter compactor, and the material will be cut and compressed. At the bottom of the cutter compactor equips with pipes with running water to cooling the material
Electricity Saving: 0.29-0.30kwh/kg
