Description of the process /
The material is conveyed to the compactor by a metal-detecting infeed conveyor.
In the compactor, the material is cut and heated to dry it and optimize the extruder feed.
Optionally , a side feeder can be used for dry, rigid and shredded materials.
In the extruder the material is melted, plasticized and homogenized. The screw design is key for optimum plasticization and production.
The molten material is filtered to remove impurities such as contaminants or infusions.
The filtered material is transferred to the second extruder in the form of threads to increase the contact surface with the high vacuum. This results in enormous degassing power and removal of volatiles.
In the second extruder, the gas-free material is conveyed to the pelletizing stage. Optionally, a second fine filtration stage can be added .
The gas-free molten material is pelletized and cooled with water.
The pellets are conveyed to a vibrating screen to separate particles of inadequate size and the cooling water is returned to the cutter.
After being screened, the pellets are dried in a centrifuge before being transported by a turbine.
Finally, different technologies are used to calculate production in real time and the pellets are stored.
Embedded technologies /
High degassing power
- Large exchange surface: duplo machines incorporate a specific technology to increase exponentially the contact surface of the molten polymer with the high vacuum.
the contact surface of the molten polymer with the high vacuum.
-High Vacuum: We incorporate high vacuum systems that reach absolute pressures up to 5 mbar.
- High flow: to remove a large amount of volatiles, they must be quickly drawn into an external condenser.
